Like others I sadly could not get the game to run. I also tried to put it in the D drive as stated in another comment but it still would not run :(

Try to run it from a disk D:, a flash card or try to download v1.1 from this mirror link: https://drive.google.com/file/d/1O7um4rRT-lbBP1hmQlja0Jm5RWfoGjWy/view?usp=sharing
It should help you!
