This sounds like it might be a problem with Vista's security settings. You'll need to be administrator to play the game from within the c:\program files(x86) folder. Instead of copying the game into C:\Program Files (x86)\LucasArts\grim\ copy the game into c:\users\[username]\documents\grim. This way you will have full ownership of the folder, shouldn't need to be administrator to play the game, and shouldn't get any problems with security.
I haven't tried playing the game with all the files installed into this directory, I don't know if it works or not but give it a try. If it does not work then take ownership of C:\Program Files (x86)\LucasArts\grim\. Check microsoft.com for full instructions on how to take ownership of a folder.
