How to fix

 
First Go to the bottom left of your desktop and type in the Search Bar “%appdata%” 
 
 
 
Once in the folder, find the folder named “Atari” and open it 
 
 
 
Then open the folder called “RCT3” then find and open “Options.txt” 
 
 
 
Now delete all of the text in there and replace it with this

Once all that is in there save and close the file and now Launch RCT3 
 
note: Before loading a park make sure to change the in game grahics setting to match your PC specs 
 
 

What causes this Error

 
I don’t quite know for sure but this error seems to pop up after changing the game Resolution to a low amount. 
 
If your on a slow PC the game can automatically change the Resolution to a low number, causing the game to crash 
 
Do not change the Graphics Settings to “High Performance” the game will crash and give the error again!
