|Are they Vista compatible? Does your system meet the minimum requirements for both Vista and the game? If you have on board graphics, you wont meet the requirements for either. |
You give no indication regarding the spec of the computer.
If the computer, especially the graphics and memory meet the requirements, (at least 2 gigs ram, 512megs graphics) try running the install or the program in compatibility mode. It could possibly be a problem relating to the User Access control in Vista. Try turning that off via control panel.
Vista is very fussy as far as system specs are concerned, XP is still the most tolerant with Windows 7 next.
