I'm using Windows Vista Ultimate. For some reason, whenever I try to install games via CD's like World of Warcraft or Diablo, it Auto Plays using explore and all the install files are for Mac! It even has an apple on the CD drive when I put the game CD's in. I assure you these CDs are for windows, as they install for Windows XP just fine. I can not fathom what the problem is. Any ideas?
