Quite simply the installation is really bugging out.

Originally tried installing and got an error message telling me i was not allowed to, and needed to be an administrator. After promptly becoming one, i tried the installation process again, and after its begening thing, the 'Installshield Wizard', it asks me about uninstalling the game, and if i'm sure i wish to remove the program completely. After of course trying with both yes and no, i recieved the same error message either way telling me i needed to have the game installed before it could do that.

Not like it's going to matter a whole lot, using XP, not vista.
