Map Editor Error

For some reason I’m having issues opening the map editor. I keep getting this message:

I’ve tried re-downloading it multiple times, putting it in it’s own folder, making it a portable application, and closed out everything else I was doing while starting up. My laptop runs Windows 8.1. Does anyone else have this issue or know how to fix this problem?

The map editor is retired from development at the moment. I would recommend to make a house in game to take a shot of the map editor with the latest tileset updates.
