Im having the same problem the installer starts but i dont know if it worked and if it did where is it i tried running the .application no luck i dont get it it looks so good i would love to try it
I realize that this is a bit late but I tried the installer version. It prompted me for admin credentials to install XNA redistributable and then it stopped. Same when I pressed the launcher button again.
What works for me is: Going to local files and starting setup.exe or just starting the .application file.
