H2V on XP?

[Mantis]

I don't suppose anybody knows how to *uninstall* Halo 2 on XP?

I forgot to select full install, so I'm left with a botched copy I can't do anything with really.

The uninstall in add/remove doesn't do anything, and although I manually removed all registry keys related to H2 I could find, I'm not able to access the install options menu.

Damnit, maybe I should have stuck to playing on Vista!

Any help is appreciated!

Well, after reinstalling SP2 several times trying to sort things out (I didn't have SP2 previous to this, and it's required) I can't even access the install menu (files may be missing or damaged or whatever), I've given up.

24 hours of trying and not getting past the first menu, and now not being able to launch the installer.

Epic fail. =(
