  3. Next, Click Start > Run and, again, in the open box type “Regedit“. Press enter
  4. In the window that appears (Registry editing window – be very careful, take care not to alter anything as this is the centre of the Windows operating system), go to this key “HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services
  5. Click on the MSIServer
  6. In the right hand pane should be an option for ImagePath. Right click this entry and select “Modify
  7. (You will need the location of Msiexec.exe now) Type the location of the Msiexec.exe file into the Value Data field and type /V directly after it. (Eg C:\Windows\system32\Msiexec.exe /V). Click OK
  8. You can now close the Registry editor window
  9. Restart PC in safe mode (Press F8 before Windows Splash Screen appears and select Safe Mode from list)
  10. Click Start > Run and type “msiexec /regserver”. Press enter
