When it's full screened, it's a really low resolution (but it's set at 1920x1080) and keeps the mouse in a small box in the upper left part of the screen.
When it's windowed, the mouse isn't locked to the window and while playing the mouse will leave the window and click on random things.
Deleting everything and reinstalling didn't work.
Edit: I found the cause. I was running MSI's Gaming App for my video card. Disabled that and the game opened and works normally.
