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

Postup řešení

1. 1 Press Windows key + R to open the Run dialog. Type 'sfc /scannow' (without quotes) and press Enter. This runs the System File Checker, which scans all protected system files and replaces corrupted ones with a cached copy. This step is crucial because a corrupted signed binary can trigger this error, and SFC will repair it.
2. 2 If SFC finds issues but cannot fix them, open Command Prompt as Administrator (press Win+X, then select 'Terminal (Admin)' or 'Command Prompt (Admin)'). Type 'DISM /Online /Cleanup-Image /RestoreHealth' and press Enter. DISM (Deployment Image Servicing and Management) repairs the Windows system image, which SFC relies on. This is like fixing the foundation before repairing the walls.
3. 3 Check if the error is caused by a specific program. If you know which application triggered the error, try reinstalling it. First, uninstall it via Settings → Apps → Installed apps, then download the latest version from the official website and install it. Reinstalling ensures the signed binary is replaced with a fresh, untampered copy.
4. 4 Temporarily disable third-party antivirus or security software. Some security tools interfere with file modifications, even for signed binaries. Right-click the antivirus icon in the system tray and select 'Disable' or 'Pause protection'. Then try the operation that caused the error. Remember to re-enable it afterward.
5. 5 If the error persists, use the Windows Update Troubleshooter: Press Win+I to open Settings, go to System → Troubleshoot → Other troubleshooters, and click 'Run' next to 'Windows Update'. This tool automatically detects and fixes common update-related issues, including permission problems that might block file modifications.
