I am running Real Myst on a Windows 7 Home Premium 64 bit system, using a core i7 processor wiith 6 GB of RAM. After about 10 minutes of running during which time Myst functions beautifully, the game will suddenly crash to the desktop without any warning. Any suggestions?

Thank you very much, Ralackk - running as administrator did not help before, but adding Windows XP service pack 3 compatability mode seemed to do the trick and I left run as administrator checked. The graphics also improved as a bonus.

I have tried the compatibility options. I get an error missing a file win_int.dat try to reinstall.
I have done that. I still am getting the same error.

I'm running on windows 10 and the program loads and plays until I get down into the cave and press the fountain button, then the program crashes (3 time now)! What's happening?

Same problem here: Windows 10, suuuuuper laggy as soon as you face the dock antechamber or try to read Atrus' note to Catherine, then crashes. I tried bottoming out the graphics/textures, but that did NOT help. Any remedies?

Thanks Ralack and Iherman - I run Win 10 AMD Phenom II X 6 and 16 gigabyte ram. The game crashed after about 10 minutes, Compability mode = win XP Service Pack 3 + running as admin solved it AND better graphics as a bonus. No lagg whatsover after about about one hour in the game - and no crashes!!! Thank you!
