Check 1: Are you running the same copy of Klavaro?

This is the most common cause by far. An installed copy of Klavaro and an extracted portable copy — the kind you make by unpacking the installer as the portable guide describes — each live in their own context. If you practised all week with the extracted copy and today opened the Start-menu installation, the installed copy legitimately shows a fresh, empty course. Nothing was deleted; you are just looking at the other copy. Decide which one is yours, always launch that one, and remove shortcuts that point elsewhere.

Check 2: Same Windows user account?

Desktop programs keep their per-user data under the account you are signed in with. If the computer has several Windows accounts — a shared family PC, a work and personal login — and you practised signed in as one user, signing in as another can show an empty history. Confirm you are on the same account you practised with before you conclude anything is lost.

Check 3: Did the lesson actually finish?

Charts and scores reflect completed work. If you closed Klavaro in the middle of a lesson, check whether that partial run was ever recorded: complete a short lesson in full, close the program, reopen it and look at the charts. If the completed lesson is there, your saving works fine and the habit to adopt is simply finishing lessons before you close the program — especially in the Fluidness module, where runs are longer paragraphs.

Check 4: Is the copy running from a place that can change?

If your copy runs from a USB stick or another removable drive, that drive can be removed, plugged into a different port or assigned a different drive letter between sessions — and a folder that was tidied up, renamed or re-extracted is effectively a new copy. For progress you care about, the boring solution is the reliable one: install Klavaro on the computer from the download page and practise with the installed copy, keeping the USB version for occasional use away from home. The Windows guide covers the standard install.

If the charts are empty but the lessons work

When the program runs, your layout and settings are right, and you complete lessons — yet charts stay empty across several sessions of the same copy and the same account — treat the installation itself as suspect. Reinstall cleanly over the top from a verified installer; Is Klavaro safe? shows how to verify the download first. Then complete one short lesson and confirm it appears. Persistent weirdness after a verified reinstall is worth reporting on the project’s SourceForge page with your version and Windows release noted.

The rest of this series — won’t open, SmartScreen, layout and scaling fixes — is collected on the troubleshooting hub.

A two-second habit that prevents the scare

Once your progress is visible again, protect it with one habit: at the end of a session, glance at the progress charts before you close Klavaro. Seeing today’s lesson land in the chart confirms that this copy, on this account, is recording properly. If a future session ever opens empty, you will know immediately that something about how you launched the program changed — a different shortcut, a different account, a moved folder — and you can retrace it with the checks above instead of assuming weeks of practice vanished.

Frequently Asked Questions

Why does Klavaro show no progress when I reopen it?

The most common explanation is that you are not running the same copy of the program. An installed copy and an extracted portable copy each keep their own context, so switching between them can make progress look lost. Pick one copy, ideally the installed one, and always practise with it.

Does Klavaro save an unfinished lesson?

Do not count on it. If you close the program in the middle of a lesson, check whether that run appears by completing a short lesson in full, closing Klavaro and reopening it. Finishing lessons completely before you close the program is the reliable habit.

Can using a different Windows account hide my progress?

Yes, that is a realistic check: desktop programs keep per-user data, so signing into Windows with a different account can show an empty course history. Make sure you are signed in with the same Windows user account you practised with.

I run Klavaro from a USB stick. Could that lose my progress?

It can if the stick is removed, remounted with a different drive letter, or the extracted copy is replaced by a fresh one. If progress matters to you, install Klavaro on the computer instead of running an extracted copy from removable media, or always run the exact same folder.

Why this happens: two selectors, one truth

Think of it as two translations stacked on top of each other. Windows translates a physical key into a character according to the Windows input language (say, French AZERTY). Klavaro then interprets what it receives according to the layout you selected in the program (say, US QWERTY). If both are AZERTY, the chain agrees and the letters match your keyboard. If one says QWERTY and the other says AZERTY, Q becomes A, A becomes Q, and a handful of other keys scatter — exactly the symptom that brings most readers here.

Fix 1: Set Klavaro’s layout selector

Look at the layout selector in the top-right corner of the Klavaro window. Set it to the layout printed on your physical keyboard — QWERTY, AZERTY, QWERTZ, Dvorak, Colemak or whichever you actually type on. This selection drives the lessons and charts Klavaro generates, which is why the program ships with so many layouts built in: the Basic Course guide explains how the course is generated from whichever layout you pick.

Fix 2: Set the Windows input language to match

Now check the language indicator on the Windows taskbar, near the clock — it shows the current input language, such as ENG or FRA. If it does not match your physical keyboard, click it (or press the Windows key plus Space) and choose the matching entry. People who type in two languages hit this constantly: Windows may have been switched for another app, and Klavaro simply inherits the mismatch. Both selectors must name the same layout at the same time.

Fix 3: Check the keyboard setting inside Klavaro

While you are in the program, also check the keyboard type setting in Klavaro’s options. It tells the program what kind of keyboard to assume, and a wrong choice there can produce odd behaviour for specific keys even when the main layout is right — particularly characters reached with modifier or dead keys on international layouts. Set it to the option that describes your hardware, then retest.

Test it in thirty seconds

Open the Basic Course and type a few letters slowly, watching each character land. If the on-screen characters now match the keys under your fingers, the mismatch is fixed and every module will behave. If only one or two special characters misbehave while letters are correct, that is not a layout problem — see special characters not counting instead. And if you deliberately want to learn a new layout such as Dvorak, the method is the mirror image: switch both Windows and Klavaro to that layout together, as the site’s layout guides explain.

More fixes live on the troubleshooting hub, and a clean copy of the program is always on the download page if yours came from somewhere else.

The QWERTZ version of the same problem

German QWERTZ users meet a subtler variant: most letters match QWERTY, but Y and Z trade places. If only those two letters come out swapped in Klavaro, you do not have a broken keyboard — one of the two selectors is set to QWERTY while the other is on QWERTZ. The same applies to smaller drifts, like a punctuation key producing the wrong symbol. The pattern to remember is simple: several wrong characters always means a layout disagreement somewhere in the chain, while a single character failing on its own points to the character-specific issues covered in the guide linked above.

Readers working on a French or German keyboard have dedicated help, too: our AZERTY typing guide covers the French layout, while the QWERTZ typing guide explains German key positions, special characters, and how to practise without fighting the wrong layout map.

Frequently Asked Questions

Why do I get different letters than the keys I press in Klavaro?

Because two layout settings are involved: the layout selected inside Klavaro and the input language Windows is using. If they disagree, for example Klavaro set to QWERTY while Windows types AZERTY, the same physical key produces a different character than the lesson expects.

What is the quickest way to fix wrong characters?

Look at the layout selector in Klavaro’s top-right corner and set it to the layout printed on your physical keyboard, then check the language indicator on the Windows taskbar and switch Windows to the matching input language. When both agree, the wrong characters stop.

How do I switch the Windows keyboard layout quickly?

Press the Windows key plus Space to cycle through the input languages installed on your system, and watch the indicator on the taskbar change. Pick the entry that matches your physical keyboard, then go back to Klavaro and test a few keys in the Basic Course.

Does Klavaro support AZERTY and QWERTZ keyboards?

Yes. Klavaro generates its course from the layout you select, and the built-in options include AZERTY and QWERTZ alongside QWERTY variants, Dvorak and Colemak. The catch is only that the in-app selection and the Windows input language must be the same layout at the same time.

The known case: µ in lesson 42

The report comes from a user review posted on the SourceForge project page, where the reviewer otherwise praises the program but notes that lesson 42 contains a µ character that does not count. We cite it for what it is: a real user reporting a character-specific problem in a specific lesson. There is no published fix we can point you to, and we will not invent one. If you hit the same wall, it is almost certainly this known quirk rather than anything you are doing wrong — and it affects that character in that context, not your whole course.

Workarounds that keep you moving

• Complete the lessons around it. One stubborn character in one lesson does not block the course. Finish the surrounding lessons and come back later if you want another try.
• Practise the character in material you control. Import a short plain-text file containing the character into the Velocity or Fluidness module, or watch for it in Adaptability drills, so the key itself still gets trained even if one lesson miscounts it.
• Report it properly. The project’s issue tracker on SourceForge is where a fix would come from. Include the lesson number, the character, the layout you selected in Klavaro and your version — those details make a report actionable.

Dead key or app quirk? Separate the causes

1. Test the key in another program. Open any text editor and type the character. If it fails there too, the problem is your keyboard, its driver, or your layout setting — not Klavaro.
2. Test the key in Klavaro’s Basic Course. The Basic Course exercises raw key positions. If the character works there but not in one particular lesson, you are looking at a lesson-specific quirk like the µ case.
3. Check the layout match. Some “dead” characters are really layout mismatches: the character lives on a different key (or needs a dead-key combination) in the layout you selected. If several characters are wrong at once, go straight to the wrong characters guide — that is the more likely cause.

Dead keys and imported texts

On many layouts, accented characters are produced with dead keys — you press the accent, then the letter. If you import your own texts for the Velocity or Fluidness modules, save them in UTF-8 encoding so accented and special characters display correctly, as the complete Klavaro walkthrough notes. A character that shows as a wrong symbol on screen is an encoding problem, which is a different fix from a character that displays fine but does not count.

For the full set of fixes in this area, see the troubleshooting hub, and grab a fresh copy from the download page if you suspect your installation is old or damaged.

A note on expectations

Klavaro is a small community-maintained project covering dozens of layouts and languages, which makes character-level edge cases in specific lessons almost inevitable — and slow to be fixed, since reports depend on users who type those layouts. That is the honest trade-off of free, open-source software. The µ report in lesson 42 has been visible on the project page without stopping the program’s otherwise strong reviews, and none of the workarounds above cost you any real training: the keys around a stubborn character still get learned, and one lesson is a tiny fraction of the course.

Frequently Asked Questions

Why does the µ character not count in Klavaro lesson 42?

A user review on Klavaro’s SourceForge project page reports exactly this: in lesson 42 the µ sign does not register. It appears to be a character-specific quirk in that lesson rather than a problem with your keyboard. No official fix has been published, so treat it as a known issue, not something you caused.

How can I keep practising if one character will not count?

Complete the lessons around the problem one, and practise the character in material you control: import a short text containing it into the Velocity or Fluidness module, or drill it in Adaptability. Your course progress does not depend on a single stubborn character.

How do I tell a dead key from a Klavaro issue?

Test the same key in another program, such as a text editor. If it fails everywhere, the keyboard or its layout setting is the problem. If it works elsewhere but not in one Klavaro lesson, and other keys work in that lesson, you are looking at a lesson-specific character quirk.

Where do I report a character that does not count?

On the issue tracker of Klavaro’s official SourceForge project. Include the lesson number, the character, the keyboard layout you selected in Klavaro and your program version, because those details are what a developer needs to reproduce it.

Why this happens on high-DPI screens

Modern laptop and monitor panels pack far more pixels than the displays older desktop software was designed for. Windows normally compensates by scaling programs up, but it chooses how to handle each program, and some applications end up drawn pixel-for-pixel — which on a dense panel means a window with very small text. Nothing inside Klavaro’s own settings controls this; the remedy lives in the program’s properties in Windows.

The fix, step by step

1. Close Klavaro completely.
2. Right-click the Klavaro shortcut on your desktop or in the Start menu, and choose Properties.
3. Open the Compatibility tab.
4. Click Change high DPI settings.
5. Tick Override high DPI scaling behavior.
6. In the “Scaling performed by” dropdown, choose System (Enhanced).
7. Click OK, then Apply, and reopen Klavaro.

The window now follows your Windows display scale, so the lesson text, menus and charts come up at the same comfortable size as the rest of your desktop. If the result looks slightly soft rather than razor sharp, that is the normal trade-off of this scaling mode and is expected.

Using the portable or extracted copy?

The override is stored against a shortcut or a program file, not inside Klavaro itself. So if you run the do-it-yourself portable copy described in our portable Klavaro guide, right-click klavaro.exe in its folder, open Properties, and apply the same Compatibility settings to the .exe directly. Each shortcut and each copy has its own setting, which is why the fix can appear to “not stick” if you later launch Klavaro a different way.

Two more display checks worth doing

• Your Windows display scale. In Settings under System and Display, most high-DPI laptops are comfortable at 125% or 150%. If the whole desktop feels small, raising the system scale fixes Klavaro along with everything else, and you may not need the override at all.
• External monitors with different densities. If you move the Klavaro window between a laptop panel and an external monitor, Windows may re-scale it per screen. Closing and reopening Klavaro on the screen where you will practise gives it a clean start at that screen’s density.

Once the text is readable, you can get on with practising — the Basic Course guide picks up from there. And if the program does not open at all rather than merely looking small, that is a different fix: see Klavaro won’t open on Windows or the troubleshooting hub.

If “System (Enhanced)” is not offered

On older Windows 10 builds the dropdown may only offer “Application” and “System”. If “System (Enhanced)” is missing, choose “System” instead — it applies the same idea with slightly softer rendering. And if Klavaro looked correct before a Windows or graphics-driver update and only went small afterwards, it is still worth re-checking this dialog: updates occasionally reset per-program compatibility choices, and re-ticking the override restores your earlier setup.

The override scales the whole window

Because the setting applies to the program as a whole, it fixes everything at once: lesson text, menus, buttons and the progress charts all scale together. There is no separate Klavaro option you need to find afterwards. If only one element still looks off after the override — most commonly the window opening small on a second monitor — drag the window fully onto the screen you will use, close it there, and reopen it, so Windows stores its position and scaling for that display.

None of this is a Klavaro setting

Worth repeating, because readers often hunt through Klavaro’s menus for a zoom or font-size option: there is nothing to find. The program simply opens at the size Windows hands it, which is why the Compatibility dialog — a Windows feature, not a Klavaro feature — is where the fix lives, and why the same override works for the shortcut, the Start-menu entry and the portable .exe alike.

Frequently Asked Questions

Why is Klavaro’s text so small on my screen?

On high-resolution displays Windows scales programs in different ways, and some apps end up rendered at a small physical size instead of following your display scaling. Klavaro can be affected on high-DPI screens. The fix is a per-program Windows setting, so you only change it for Klavaro.

What exactly do I change to fix the small text?

Right-click the Klavaro shortcut, open Properties, go to the Compatibility tab and click “Change high DPI settings”. Tick “Override high DPI scaling behavior” and choose “System (Enhanced)” in the dropdown, then apply and reopen Klavaro. The interface then follows your Windows display scaling.

Does the DPI fix work for the portable version too?

Yes. The setting lives on the shortcut or the program file, not inside Klavaro. For an extracted portable copy, right-click klavaro.exe itself, open Properties and apply the same Compatibility settings to it.

Will the high-DPI override affect my other programs?

No. The override is stored per shortcut or per program file, so it changes scaling only for Klavaro. If you ever want to undo it, reopen the same dialog and untick the override box.

What SmartScreen is actually checking

SmartScreen looks for a digital signature that ties a program to a verified publisher. Commercial developers buy a code-signing certificate and sign their installers, so Windows can display a publisher name. Klavaro is free, open-source software maintained by a single developer, Felipe E. F. de Castro, who ships the installer unsigned. Without a signature, Windows treats the file as unknown and shows the warning to everyone, including people who downloaded the perfectly genuine release from the official SourceForge project. The message says nothing about the file being harmful; it says Windows does not know who published it.

How to run the installer anyway

1. On the blue “Windows protected your PC” screen, click More info. The screen expands and shows details about the file.
2. Check that the file name shown is the official installer, klavaro-3.13-win-setup.exe.
3. Click Run anyway. The installer starts normally and you can complete the setup as described in the Klavaro for Windows guide.

You will only go through this once, at installation time. Starting the installed program afterwards does not bring the warning back, so if Klavaro seems blocked every day, something else is going on — work through Klavaro won’t open instead.

Verify first, then bypass with confidence

“Run anyway” is a reasonable click only when you have independent proof the file is genuine — and for Klavaro that proof takes a minute. The download page publishes the installer’s SHA-256 checksum. Compare the checksum of the file on your computer with the published value, as Is Klavaro safe? explains step by step. If the two match exactly, your file is bit-for-bit the official release, and the SmartScreen warning is just the missing certificate talking.

When you should NOT click Run anyway

• The file name is different. Anything that is not klavaro-3.13-win-setup.exe did not come from the official release, whatever the page you found it on claimed.
• You downloaded it from a random software site. Third-party download portals sometimes repackage freeware. Get the file from the official SourceForge link on our download page instead.
• The SHA-256 checksum does not match. A mismatch means the file is incomplete or altered. Delete it and download again; do not argue with a failed checksum.

These checks take less time than the warning makes you fear, and they convert a leap of faith into a verified install. For any other launch problem, the troubleshooting hub collects every fix in one place.

SmartScreen is not your antivirus

It helps to keep two different warnings apart. SmartScreen is a Windows feature and its blue screen is about reputation and signatures: it appears when you run a downloaded file Windows cannot identify. Your antivirus is a separate layer that scans for known harmful behaviour and may show its own, differently worded prompt. Klavaro can trigger the first kind simply by being unsigned freeware; triggering the second kind is less common and is exactly why the checksum check matters — a file that passes the SHA-256 comparison is the same file the project released, whatever a scanner guesses about it.

Windows 10 and Windows 11 behave the same way

The dialog looks slightly different between Windows versions, but the flow is identical on both: the warning hides the way forward behind the “More info” link, and “Run anyway” appears only after you click it. If you do not see a “Run anyway” button at all, you are probably looking at a stricter block — for example a file your organisation’s policy forbids — which is an administrator matter, not something to work around.

Frequently Asked Questions

Why does Windows say it protected my PC from Klavaro?

SmartScreen warns about programs it does not recognize. Klavaro’s developer releases the installer without a paid code-signing certificate, so Windows cannot verify a publisher name and shows the warning for the genuine file. The warning is about the missing certificate, not about anything the program did.

How do I run the Klavaro installer past SmartScreen?

On the blue warning screen, click “More info” and then “Run anyway”. Windows then starts the installer normally. You only need to do this once, when installing; the warning does not appear every time you open the program.

When should I NOT click Run anyway?

If the file name is not klavaro-3.13-win-setup.exe, if the file came from a random download site instead of the official SourceForge release, or if its SHA-256 checksum does not match the value published on this site’s download page. In those cases delete the file and download again from the official source.

Is it safe to bypass SmartScreen for Klavaro?

Yes, when you have verified the file first. Download from the official link on this site, compare the SHA-256 checksum with the published value, and only then choose Run anyway. That combination gives you the same assurance the missing certificate would have provided.

Check 1: Is a security prompt waiting for you?

Double-click the installer or the program, then look carefully — including at the taskbar — for a window asking a question. The SmartScreen warning, “Windows protected your PC”, sometimes opens behind your browser or file explorer, and while it waits, nothing else happens, which looks exactly like a program that refuses to start. If you see that blue screen, click “More info” and then “Run anyway”; the full explanation of why Windows shows it for the genuine installer is in our SmartScreen guide. Also glance at your antivirus: if it quarantined the installer, Klavaro cannot open until you allow it.

Check 2: Restart once, then try the Start menu

Restart Windows before you try anything more technical. A half-finished update or a stuck process can block a small GTK program from creating its window. After the restart, open Klavaro from the Start menu entry created by the installer rather than from a shortcut you made yourself, so you know you are testing the real installed copy.

Check 3: Are you running the installed copy?

If you downloaded the installer and also experimented with an extracted folder — the do-it-yourself portable method described in our portable Klavaro guide — it is easy to launch the wrong thing. An extracted copy sitting somewhere temporary, or on a USB stick that is not plugged in or has been assigned a different drive letter, can fail silently or start without any of your progress. Decide which copy is yours, use that one consistently, and remove shortcuts that point at the others.

Check 4: Verify the installer, then reinstall cleanly

If Klavaro opened before and suddenly will not, suspect the installation rather than Windows. Uninstall it from Settings, restart, and reinstall from a fresh download. Before running the new installer, verify it: the download page publishes the SHA-256 checksum of the official installer, and our verification guide shows how to compare it with the file on your disk. If the checksum does not match, delete the file — an antivirus false positive is only a safe assumption once the hash proves the file is the genuine release.

Check 5: Compatibility mode, for very old setups

Only if the checks above fail and you are on an unusual setup: right-click the Klavaro shortcut, open Properties and the Compatibility tab, and try running the program in compatibility mode for an earlier Windows version. On a normal Windows 10 or 11 machine this should not be necessary, and current versions of Klavaro are built for modern Windows as the Windows setup guide describes — treat compatibility mode as a last resort, not a first step, and undo it if it makes no difference.

When it opens but looks broken

A window that opens with minuscule text is a different problem with its own quick fix: the high-DPI scaling override. A window that opens but types the wrong letters is a layout mismatch, covered in the wrong characters guide. And if Klavaro opens fine but your practice history is empty, work through the progress checks instead of reinstalling. The full list of fixes lives on the troubleshooting hub.

Check 6: The shortcut itself may be the problem

If Klavaro opens from the Start menu but not from your desktop or taskbar shortcut, the shortcut is pointing at something that no longer exists — an old install location, or an extracted folder you deleted after experimenting with the portable method. Delete the shortcut, open Klavaro once from the Start menu, and if you want a shortcut, create a fresh one from the working entry. This one catches people out because the broken shortcut looks identical to a working one; the only symptom is a program that “will not open” when started one particular way.

Frequently Asked Questions

Why does nothing happen when I double-click Klavaro?

The most common reason is a Windows prompt waiting for your answer, such as the SmartScreen warning, which can appear behind other windows. If no prompt appears, try opening the installed copy from the Start menu instead of an extracted folder, and restart the computer once before reinstalling.

Should I run Klavaro as administrator to make it open?

Normally no. Klavaro is a small desktop program that runs fine under a standard user account once it is installed. If it only opens with administrator rights, that usually points to a damaged install or a copy sitting in a protected location, and a clean reinstall is the better fix.

Will reinstalling Klavaro delete my progress?

Reinstalling replaces the program files. To be safe, treat your progress as tied to how you run the program: if you have been practising with an extracted portable copy, keep using that same copy, because switching between the installed and extracted versions can make progress look as if it vanished.

Can an antivirus stop Klavaro from opening?

It can happen with unsigned freeware: an antivirus may quarantine the installer or the program before it starts. Verify the installer’s SHA-256 checksum against the value published on the download page. If it matches, the file is the genuine official release and you can allow it in your antivirus.

First, match your symptom to a fix

• Nothing happens when you open Klavaro, or it closes immediately → Klavaro won’t open on Windows
• A blue “Windows protected your PC” screen appears when you run the installer → the SmartScreen warning explained
• The text in the window is tiny on a high-resolution screen → the high-DPI scaling fix
• Certain characters never count in a lesson, like the µ sign → special characters not counting
• You press one key and a different letter appears → wrong characters and layout mismatch
• Your charts and scores are empty when you come back → progress not saved: the checks

The five-minute check sequence

If your symptom is not obvious, run these checks in order before you change anything bigger. Most “Klavaro is broken” reports are resolved by step two or three.

1. Restart the computer and try again. A pending Windows update or a stuck background process can stop a small program from opening, and a restart rules that out in one step.
2. Open the installed copy from the Start menu. If you have been running Klavaro from an extracted folder, a download folder or a USB stick, open the version you actually installed instead. Switching between copies causes several confusing symptoms, including missing progress.
3. Watch for a Windows prompt. When you run the installer, Windows may show the SmartScreen warning; when you launch the program the first time, your antivirus may ask a question too. If a prompt is waiting behind other windows, the program looks dead when it is really just waiting. Our SmartScreen guide shows exactly which buttons to click.
4. Check the layout selector. If the program opens but typing feels wrong, look at the layout shown in Klavaro’s top-right corner and confirm it matches your physical keyboard and the Windows input language.
5. Reinstall cleanly, but only now. If the checks above did not help, uninstall Klavaro and install it again from the download page, which links the official SourceForge installer.

Verify the file before you blame the program

A surprising number of problems start before Klavaro is even installed: an interrupted download or a file from an unofficial site. The download page publishes the installer’s SHA-256 checksum precisely so you can rule this out. Our guide Is Klavaro safe? walks through comparing the checksum of the file on your disk with the published value. If the two do not match, delete the file and download again from the official link — no other fix is worth trying on a file you cannot trust.

Reinstalling the right way

When a reinstall is the answer, keep it simple: uninstall from Windows Settings, restart, then run the verified installer and let it install to its default location. Avoid installing over an old extracted copy in a random folder, and afterwards always launch the same installed copy. On Windows 10 and 11 no special compatibility settings are normally needed; the Klavaro for Windows guide covers the standard setup, including the portable option if you deliberately want one.

Still stuck after all of this?

Write down three details before you search further or ask for help: your Windows version, where you downloaded Klavaro from, and exactly what happens — including the text of any message. “It shows a blue Windows warning” points to SmartScreen; “the window opens but letters are wrong” points to the layout guide. Precise symptoms get precise fixes, and every guide in this section starts from one.

Frequently Asked Questions

What should I try first when Klavaro stops working?

Restart your computer, then open the installed copy of Klavaro from the Start menu. After that, work through the checks in order: let the program past SmartScreen if Windows shows the warning, confirm your keyboard layout matches, and only reinstall once the simple checks are done.

Is reinstalling Klavaro a safe fix?

Yes, if you reinstall from the official installer on this site’s download page and verify the file first. Klavaro is a small program, so a clean reinstall takes a minute and replaces any damaged or moved program files. The download page publishes the SHA-256 checksum so you can confirm the installer is genuine.

Where can I check that my Klavaro download is genuine?

On the download page of this site, which links the official SourceForge installer and publishes its SHA-256 checksum. Our guide to verifying the download walks through comparing the checksum of your file with the published value before you run it.

Which Klavaro problems have their own detailed guides?

The ones readers hit most: Klavaro won’t open on Windows, the SmartScreen warning, text that is too small on high-DPI screens, special characters that do not count, wrong characters from a layout mismatch, and progress that does not seem to save. Each has a dedicated fix guide linked from this page.
