Cannot Turn Windows Features On or Off

[Guest RECKERR]

I am using Windows Vista Business Edition. I am trying to install Games and

other features, but when I select any of the options in "Turn Windows

Features On or Off", nothing happens. The window with "Please wait while the

features are configured" appears for a few seconds but there is no activity.

When I check, the features have not been installed. Any advice on how to fix

this problem will be greatly appreciated. Thanks and regards.
