I am trying to install a 32 bit windows vista upgrade over a windows xp 32 bit, and the cd will not play. I bought the cd used and had it buffed out a a computer repair shop to make sure any scratches were not interfering. I can get other cd 's to play. The disk says part number x12-24190-00, and it says dvd rom. The cd player that I have is cd writer but not a dvd player, but I have dvd sftwre installed on this computer. I would appreciate any perspective.
