Roller Coaster Tycoon 3 Platinum....help

Forgive me if I posted in the wrong thread....but heres what i got....

just got the game Roller Coaster Tycoon 3 Platinum....installed, went to play, and started to load, then stopped, saying windows encounterd a problem.

After now hours of forum trolling, a couple patch downloads, and some supposed tips.....I still have a nice new shiny $20 coaster.  Anyone run into this issue, and resolve it?

I run Windows 7, and exceed all the requirements for the (now 6 years old) for the game.....I dumbed down all my graphics cards...and everything I knew and learned to do....
