Topic title pretty much says it all. My friend has vista and every game except for TS runs. When you try to run TS, it gives the "one or more dll files are missing", or something to that effect, message. One suggestion i read on some other sites was to load the game up again after that message, but it didint work. Another suggestion was to turn the User Account Control option off, and take ownership of the First Decade folder. It no longer gave the message and it loaded up, so to speak, but the screen is black and you can here the mouse rolling over the menu options. I tried going to the C&C forums, but I am unable to log in there to ask for help. If anyone can either ask for help for me, or can suggest something that might work, i would be eternally grateful.
