Error Code error-exe-cannot-modify-signed-binary — Windows 11

Postup řešení

1. 1 First, identify which program is causing the error. If it's a game mod, check if the mod is compatible with the current version of the game. Mods often break when games update, and the mod might be trying to modify a signed executable that has changed. Look for an updated version of the mod.
2. 2 If the error occurs with a legitimate program that is trying to update itself, try running the program as administrator. Right-click the executable, select 'Run as administrator'. This gives the program the necessary permissions to modify its own files. If that doesn't work, check if the program has a setting to disable signature verification or to allow self-modification.
3. 3 If the error is related to a system file, run the System File Checker to repair any corrupted files. Press Windows key + X and select 'Windows Terminal (Admin)'. Type 'sfc /scannow' and press Enter. This will replace any modified system files with the correct signed versions.
4. 4 If you are a developer and need to modify a signed binary, you must re-sign it after making changes. Use the Windows SDK's 'signtool' utility. Open a developer command prompt, navigate to the file, and use the command: 'signtool sign /f MyCert.pfx /p MyPassword MyApp.exe'. This applies a new digital signature to the modified file.
5. 5 If the error is caused by malware, run a full antivirus scan. Use Windows Security (built-in) or a trusted third-party antivirus. Malware often tries to modify signed files to hide itself. After removing the malware, the error should stop.
