Description of Error Code 0x80006A0B and Common Scenarios Where It Appears

This error may occur in several scenarios: during software installation attempts on a computer running an outdated version of the Windows Installer service; when installing updates through Microsoft’s Update platform that are incompatible with your system configuration or version of Windows; upon trying to install applications from third-party sources where there is a mismatch between the software prerequisites and what is currently installed on the machine.

Howto solve error code 0x80006A0B

  1. Check for updates: Open Control Panel, go to ‘Programs’ > ‘Windows Update’, and ensure your system is up-to-date. This might resolve the issue if it’s related to outdated components of Windows Installer.
  2. Use System File Checker (SFC): Press Win+R, type sfc /scannow, press Enter, and restart your computer after SFC has completed. This tool scans for corrupted system files and attempts to repair them automatically.
  3. Run Windows Installer Cleanup Utility: Download the latest version from Microsoft’s official website or obtain an older version that matches your operating system. Run the utility by navigating to its folder location, selecting wicuclean.exe, and following on-screen instructions to remove corrupted installations from the cache.
  4. Repair Installation of Windows Installer: From Safe Mode, open Command Prompt as Administrator and type msiexec /unreg followed by msiexec /regserver. Restart your computer after performing these commands. This process unregisters and then re-registers the Windows Installer to fix potential registry issues.
  5. Check for Corrupted Registry Keys: Use a reputable third-party tool like RegCure Pro or Glary Utilities’ Registry Repair feature to scan and clean up any corrupted registry keys that might be causing installation issues. Be cautious with this step, as making incorrect changes in the registry can cause system instability.
