Uninstall/reinstall failed - edit registry?

[G-Max]

I'm having a most peculiar problem. I tried uninstalling and reinstalling the game, and wound up with a computer on which Civ 4 is not showing up in the add/remove programs list, nor will it play even though the game files still seemed to be there. I'm guessing that it had something to do with a faulty Disc 2. So how does a Windows XP user tell his computer very insistently that the game isn't there?

(Without reformatting, of course.)

Never mind. It just required deleting about a hundred registry keys, then rebooting my computer.

Holy crap, though, this game gets installed to like three or four places..

If when you come to re-install it claims it is still installed you may also need to remove the install shield information folder:

Delete "...\Program Files\InstallShield Installation Information\{CFBCE791-2D53-4FCE-B3FB-D6E01F4112E8}" (Civ4)
Delete "...\Program Files\InstallShield Installation Information\{3E4B349F-10B5-4586-9D99-489A90A8B228}" (Warlords)
Delete "...\Program Files\InstallShield Installation Information\{32E4F0D2-C135-475E-A841-1D59A0D22989}" (BtS)
(note: InstallShield Installation Information is a hidden directory so you need to configure windows explorer to show hidden files).
