I think it's mostly renpy games, but at the moment I'm getting a lot of failing executables when I click launch. You can boot the exe from the parent directory, but in client I'm getting this. I'm not sure what 127 is but this seemed like the relevant segment of the log:

Any ideas on how I can fix this?
