When I put my Fallout Trilogy DVD-Rom into my computer, it won't start the installation process. Afterwards, I tried going to the D: Drive, but when I open the drive, it's empty with no fallout data files whatsoever. If anyone can give me some tips and help me with this problem, I'd greatly appreciate it. Oh, and by the way, my PC has the OS Windows XP and a Pentium 4 processor. It has all the necessary hardware to run this game, because I've installed it before on a laptop that I used to own. But I ended up selling that and want to continue playing. Can someone please help?
