Step2: Start the Windows Installer service. 1. Click Start, type Services.msc and press [ENTER]

2. Double-click Windows Installer.

3. Set the Startup type of Windows Installer to Manual.

4. Click Start to start the service. Note down the error message if any.

5. Click OK.

Step3:

The Windows Installer Cleanup utility deletes all files and registry settings associated with a program's Windows Installer configuration.
