Linux comes to the rescue again. I wanted to play undying. It's an old FPS/RPG from ~2002. i put it down years and years ago, It doesn't actually install any more. I know for a fact there is no problem with the disk, it's the InstallShield software that is incompatible with Windows XP. So a disk that doesn't install. No Game. I found something for Linux called 'UnShield', it is able to extract the data directly from the .CAB files. Beautiful.
