I'm also getting the "Failed to open registry key:2"
I imagine that it's failing to read/write the registry keys so it can store the location of the save files and game data.
However, that sounds like I'm bitching and I'm not
I'm VERY grateful for such a nice tool, if I can help out in any way I'd be more than happy to! Many thanks to DairyMoose for this! I appreciate all the time and effort you've put into making this
