Everytime I click on one of these (except for Desktop Background, an error message will come up saying "Windows cannot find 'C:\Windows\System32\rundll32.exe'. Make sure you typed the name correctly, and then try again."
Also, it's not letting me run one of my games (Starcraft: Brood Wars) which I could run perfectly on Vista before.
How do I fix all this? Thanks in advance.
