Apparently I'm unable to set-up Bonecraft because I need setup.msi which makes no sense to me... I can't download the game without it so if I can get some help I'd be very grateful...

ok so I did some crazy shit due to a problem (sexbot was gone for some reason...) and now I can't play Bonecraft anymore because I can't uninstall/reinstall the game... I'm thinking I have to revoke...
