I click the program and my computer crashes
From OHRRPGCE-Wiki
First, are you sure that your computer really crashed? Press ALT+TAB or CTRL+ESC and see if you jump back to the desktop. If so, CUSTOM.EXE or GAME.EXE might have locked up, but your computer did not crash. You can also try CTRL+ALT+DEL to bring up the Windows Task Manager
If the OHRRPGCE really did crash your computer, you may have found a very serious bug, and you should report it ... however, it is very unlikely that the OHRRPGCE would crash your computer, unless your computer was already suffering from some severe emotional stress (defective memory, virus infection)
