Here is some specific information about the problem.
I got the game in a 3 in 1 pack including Roller Coaster Tycoon 1, 2, and 3.
Apparently, Roller Coaster Tycoon 1 and 2 work on my Windows 7 hardware but Roller Coaster Tycoon 3 doesn't
I have tried pulling out the disk and putting it back in but it doesn't work.
Should I mention, it does show me a screen that has many lettered buttons. I always click the play button but after that the window closes and my computer just goes back to the home screen.
I made a Quick Tab to the game but when I try to open it, it does nothing.
I may try your thought that you provided me with.
I will report back if it still does not work.
