It runs; I just didn't know how to force it to run when the "Windows protected you from an unknown app" message popped up. I got that figured out later; annoying that it does that and it's not obvious how to make it run regardless.
I'm pretty sure that's your security settings rather than an issue in the game, I'll look into it though
Probably. It only does that for some of the games, though; some it just plays with no problems. Not sure why
