Though I don't think I have encountered this specific error before, I know that some people had issues to start the game because their antivirus software on newer systems blocked it (the game.exe itself is the entire game files folder packed with Enigma Virtual Box which seems to cause that issue for some). Maybe try to add the game to the antivirus exclusion/whitelist. Or try to run it in compatibility mode for: Windows XP if that first step doesn't fix it.
Yea I've read a few websites about that error, too. But it seems to appear rather random and there isn't really a fix that works for everyone. Very unfortunate.
Let's try this if you're willing to: I've uploaded a version of the game that is not boxed by the Enigma program. So you have to scroll all the way down in the game folder to the RPG_RT.exe in order to play. Maybe you can avoid the error with that. [LINK EDITED OUT]
