Be sure you have a single monitor connected to the Nvidia graphics card and to the graphics card only. If the monitor is not connected to the Nvidia graphics card, shut down the computer, move the cable to the video card, and restart the computer.

If you get one of these messages with the a single monitor connected to the Nvidia graphics card, the WMI service may be corrupt. You will need to repair the WMI service in order to get the drivers to install properly. To do so, run a Command Prompt as Administrator, then enter the following commands, pressing enter after each line:

 If that fails to solve the issue, then you will need to manually rebuild the repository by entering the following in a Command prompt as Admistrator:

1. Bring up the Windows Task Manager, and go to the Services tab. Change startup type to Window Management Instrumentation (WMI) Service to disabled

2. Stop the WMI Service; you may need to stop IP Helper Service first or other dependent services before it allows you to stop WMI Service

3. Rename the repository folder: C:\WINDOWS\system32\wbem\Repository to Repository.old
4. Open a CMD Prompt with elevated privileges and enter:
   CD windows\system32\wbem
   for /f %s in ('dir /b /s *.dll') do regsvr32 /s %s

5. Back in Task Manager, set the WMI Service type back to Automatic and start WMI Service

6. Go back to the Command Prompt and enter:
    cd /d c:\ 

Make sure the prompt shows C:\, then enter:
    for /f %s in ('dir /s /b *.mof *.mfl') do mofcomp %s

7. Reboot the Computer

You should now be able to install the Nvidia drivers.
