How to fix error error-app-init-failure in Windows 11

Solution Steps

1. 1 Press Windows key + R, type 'appwiz.cpl', and press Enter. In the Programs and Features window, look for the problematic app. Right-click it and select 'Repair' if available. This reinstalls missing or corrupted files without removing your data.
2. 2 If repair isn't available, uninstall the app completely. Go to Settings → Apps → Installed apps, find the app, click the three dots, and select 'Uninstall'. Then reinstall it from the official source. This ensures a clean installation.
3. 3 Install the latest Microsoft Visual C++ Redistributable. Go to the Microsoft website, download 'vc_redist.x64.exe' (and x86 if needed), and run it. Many apps depend on these runtime libraries.
4. 4 Install the latest .NET Framework. Go to Settings → Windows Update and check for updates. Alternatively, download the .NET Framework from Microsoft's website. This provides essential libraries for many applications.
5. 5 Press Windows key + R, type 'cmd', and press Ctrl+Shift+Enter to open Command Prompt as admin. Type 'sfc /scannow' and press Enter. This repairs system files that might be causing the issue.
6. 6 Check if the app is compatible with Windows 11. Right-click the app's shortcut, select 'Properties', go to the 'Compatibility' tab, and try running it in compatibility mode for Windows 8 or 10.
