Solution

Solution 1

Run Windows System File Checker:

(!) You will need to have Windows Installation Disc to run the utility. It is strongly recommended to boot from the disc to run the system file check. See also Microsoft Knowledge Base Article 929833.

(!) If you do not have Windows Installation Disc at hand, you can always create it within Windows. Please see How to Create a System Repair Disk in Windows 7 and Vista.

1. Hit Start-Run and type in cmd
2. In the command line, issue the following command:

   sfc.exe /scannow

   (!) You can also view detailed instructions with screenshots at How to Run the System File Checker (Sfc.exe) Offline in Windows 7 and Vista.

This will check the system for corruption and repair the corrupted system files from the Windows Installation Disc.

Solution 2

Make sure the Windows Modules Installer service is running:

1. Start -> Run -> services.msc;
2. Locate Windows Modules Installer;
3. Set up Startup Type to Manual and start the service.
