I struggled filing this problem as something belonging in the gaming or applications forum. I have an ISO of a (very new) game. When I put the cd into the drive, rather than auto playing (as every other cd does), my computer automatically opens windows explorer for the E: drive (my dvd drive). So once explorer is open I attempt to double click on the setup file that would normally install the game, but a dos window opens and then immediately closes, and nothing happens. So then I went into my computer, right clicked on the E drive hoping I could select autoplay, but that wasn't an option for the disc. Last I explored the cd again and there was an autoplay file so I double clicked on that, a dos window opens, and I get and error saying "NTVDM CPU has encountered an illegal instruction." Does anyone know what this is? I have a friend who installed the same game on his computer (which is almost identical to mine, except xp pro instead of home). He had no problems... what is it that is preventing this program from running properly?? Any suggestions would be greatly appreciated.
