Enditall2 (killer 2) works perfectly in windows XP....
what you can also try.... is when you boot up your computer, press F8 (you can start pressing it once everysecond from the moment you switch it on... until you get a menu. This menu comes BEFORE you see the "loading windows XP bar).
In this menu, choose SAFEMODE....
Let it boot, and try to install the game now....
Safemode doesnt load ANYTHING other than the bare basics windows needs to run on..., so if its software related, this will bypass it.
Try this, and let me know...
