When I first inserted the CD everything was fine and installation started right up. About halfway through though I accidentally hit the eject button on the CD drive. It interrupted my installation and closed it. Now when I reinsert the disc it tells me that the game cannot be installed until I install Windows Vista Service Pack 2. I am running Windows 7 and cannot even install that program. I also tried restarting my computer and making sure my Windows updates were current. I am even more baffled as to why I need it now and not at first. Does anyone know anything about this? Thanks!
