I installed RCT today and was quite excited, then hit this brick wall of an error. Pops up with both rct.exe and launcher.exe. I run vista 64bit and it spits this message at me:

All my attempts to run in any combination of compability modes has resulted in failure.

try to add rct.exe to the dep[data execution prevention] exclude list, i remember playing the game long time back and it would instantly crash, so i added to the dep exclude list and worked pretty well

Had the same problem and this fixed it!

So for anyone that gets the same problem :
- right click on computer (in your start menu)
- go in properties
- advanced system settings
- in the advanced tab, click settings in performance
- add the game in the Data Execution Prevention exception list

Thanks to the both of you, this got my game running. Hoping this bumps to the top for anyone else needing this help.
