You can install old versions through the app if you press the cog next to the launch button -> manage -> switch to another version
The game maximizes its window upon startup, maybe that's messing with it?
Possibly, I'm not sure though, as when I do start it, the entire screen is gray, the icon for the game isn't there and then it closes by itself after a few moments
I'll disable the auto-maximize thing for the next update and see if that fixes it.
