We actually did some testing with this ISO, and re-ripped it a few times, it seems that there's an incompatibility with modern-day operating systems. I'm pretty sure it requires x86 or less to open, as we we're only able to open this on older 32bit machines. Try setting up a simple Virtual Machine running Windows 95 - Windows 7 in 32Bit x86, and you should be able to open and run the disk. Hope that helps.
