Was on disk 3 of Civilization 4 when guess what, Vista completely froze. Had to reboot. My game is now half-installed, I can't see it in Programs and Features *Misses add or remove programs*, when I insert the game it tries to autorun the game itself.
I'm toughing it out on the Laptop until 7 comes out. XP is on my main PC, and I have no more serials left.
So if people would stop posting unhelpful, unpractical solutions... (XP could have froze just as well as Vista, and I'd be in the same situation) It'd be nice.
I figured it out. Thanks Cossak. I deleted all the game folders, then used CCleaner to delete all the unlinked dlls and such, then I went into the CD and selected the setup.exe instead of the Autorun, which let me install it.
