Click the File menu, and then click Exit Method 2: If you still experience the issue, we might have to make little changes in the registry. Click on Start, type regedit in the search box. On the Registry Editor window, navigate to: HKLM System CurrentControlSet Services MSIServer 3. IF there is an 'Enum', delete the key.
