RPG Maker XP has stopped working error
So, not one to shy away from a challenge, I came up with a solution for him. And, hopefully, if anyone else encounters this problem this'll help them as well.
Open Control Panel and click on System & Security, then click System. Click on Advanced System Settings in the left-hand panel. This will bring up the "System Properties".
Under Performance, click "Settings", thus:
System Properties
This will bring up the Performance Options. Click on the Data Execution Prevention (DEP) tab. Click Add to add RPG Maker XP to the list (making sure it's checked).
Data Execution Prevention (DEP)
When you click Ok, then Ok on the "System Properties" dialog, you should now be able to run RPG Maker XP. Also, make sure that your firewall and/or virus checker recognises it.
