Just downloaded WinCDEmu-3.6.exe to my portable external drive, copied it onto a PC running W7 Ultimate x32 (not SP1, that’s the ISO I need to mount and install). When I try to run it, it says “this isn’t a 32-bit application.” Any suggestions?

Unless someone has a better idea, I think I’ll try WinCDEmu portable, maybe I can get the install to work with SP1.
