Error message 0XC0E90002 contact system administrator

The message indicates that a program or component on the device is either corrupted, incompatible with Windows, or not installed correctly. To resolve it, follow these steps in order:

1. Restart the computer

• Fully restart Windows (not just sleep).
• If the same error appears again after restart, restart one more time.
• If the error persists after two or three restarts, continue with the next steps.

2. Reinstall the program that triggers the error

• Note which program or file name appears in the error dialog (for example, a game, utility, or other app).
• Uninstall that program from Settings > Apps > Installed apps (or Apps & features), then restart.
• Download or obtain a fresh copy of the installer from a trusted source and install it again.

3. Install all Windows Updates Some apps require Windows components (such as .NET, Visual C++ runtimes, DirectX) that are delivered via Windows Update.

• In Windows 11:
  1. Select Start.
  2. Open Settings.
  3. Go to Windows Update.
  4. Select Check for updates and install all important/available updates.
• Restart when prompted and check if the error still appears.

4. Check the disk for errors Corrupted files on disk can cause “not designed to run on Windows or it contains an error” messages.

• Open File Explorer.
• Right‑click the system drive (usually C:), select Properties.
• Go to the Tools tab and under Error-checking, select Check or Check now.
• Enable options to automatically fix file system errors and scan for bad sectors, then start the scan.
• Restart if prompted and test again.

5. Repair system files and disk from Command Prompt (advanced) If the problem continues, run built‑in repair tools:

• Open Command Prompt as administrator.
• Run:
  • chkdsk /f C: and press Enter, then accept scheduling at next restart and reboot.
  • After that completes, open Command Prompt as administrator again and run:
    • DISM.exe /Online /Cleanup-image /Restorehealth
• Restart once more and see if the error still appears.

6. If the error persists after all steps

• If the error is tied to a specific app, contact that app’s vendor and confirm Windows 11 compatibility and updated drivers.
• If the message appears at random with no clear app name, or after multiple restarts and reinstalling recent apps/updates, contact Microsoft Support for deeper investigation, as there may be a failed update or low‑level component issue.

Avoid manually editing or deleting registry keys to “fix” this; that can cause further system problems later.
