You're right Jenny100. My copy of Zork Nemesis is the 3CD Activision, for MSDOS and Win95. It probably will play on any modern Windows system but there will be a major problem with modern hardware. The game must be slowed down to be enjoyable. Use a slow-down program as mentioned earlier in this thread.
One scene in particular, requires working with a moving object. On modern equipment, that object moves so fast that you can't finish the scene correctly.
There is a patch available for this game at

EDITED
This patch adds captions to the game which is invaluable for the hearing impaired. Even if your hearing is excellent, the captions make solving some puzzles easier.
