Need help mounting FF7 ISO

I downloaded a torrent for the PC version of Final Fantasy 7, but I'm having trouble using it. It had four ISO's, one for each disc, and after looking at the contents and sizes, they're all legit. However, the only one I've been able to use is the first disc, the install disc. I installed it correctly after mounting it using Alcohol 120%, but when I tried mounting any of the game discs, Windows XP wanted to open the video files on the disc (and didn't allow AutoPlay to choose the .exe), and when I tried using the .exe, it said to insert the disc. I also tried Daemon tools with the same results. I also tried patching the .exe, and still nothing

Should I just burn each ISO to a separate disc and try to run the .exe when I have a disc in the drive? Or is there some solution (possibly unique to this game) that I need to do?

 

Nevermind, I tried burning the image to a CD with Nero and I still get the same message.
