Solution Steps
- 1 Press Windows key + R, type 'services.msc', and press Enter. Find 'Windows Installer'. Double-click it, set 'Startup type' to 'Manual', and click 'Start' if it's not running. Click 'Apply' and 'OK'. This ensures the service is available when needed.
- 2 Press Windows key + X and select 'Terminal (Admin)'. Type 'sfc /scannow' and press Enter. This scans for corrupted system files that might affect the installer service.
- 3 In the same terminal, type 'DISM /Online /Cleanup-Image /RestoreHealth' and press Enter. This repairs the system image, which can fix underlying issues.
- 4 Check if the Windows Installer service is being blocked by Group Policy. Press Windows key + R, type 'gpedit.msc' (if available), and navigate to Computer Configuration → Administrative Templates → Windows Components → Windows Installer. Ensure 'Turn off Windows Installer' is set to 'Not Configured'.
- 5 If the error persists, re-register the Windows Installer service by typing 'msiexec /unregister' and then 'msiexec /regserver' in an admin terminal.
