Hello Paul,
This problem occurs when Windows Management Instrumentation (WMI) is not
working correctly on a Windows Vista-based computer.
You could try this:
Ñight-click Command Prompt (in Start Menu\Programs\Accessories) and choose
Run as Administrator. Type (or Copy and Paste) the following command:
winmgmt /verifyrepository
If the system returns "WMI repository is not consistent", type this command:
winmgmt /salvagerepository
The first time you run this it will fail. (It will issue stop commands to
the services causing it to fail, saying, "A stop control has been sent to a
service that other running services are dependent on").
It might take a couple minutes for the services to shut down.
Run the last command again.
You actually may have to run it 3 times before it finally runs and completes
on its own.
