Alright, I was able to get the other games working sorta, but only with the CD-ROM inserted. Copying the files to the hard drive didn't work.
To show how little effort was put into this software "pack", two of the games install different versions of QuickTime which are
incompatible with each other. I had to manually delete the DLLs for both versions of QuickTime (as it does not include an uninstaller) and reinstall only one of them.
