Just reinstalled Windows7 to confirm everything xD Indeed, just one .exe file . It should open by itself. You might be missing some libraries (prepacked files groups for many programs to use) on Your computer. Problem is, without asking the creator of the game, it’ll be hard to pinpont, what’s necessary for it to open and what is missing. Try this:
- right-click on the file, open Properties, then Compatibility.
- select Windows 7, and if that doesn’t help, let Windows decide what parameters it needs. There should be some Help option for that, but memory escapes me.
If nothing of this works, I’ll be out of ideas, bro. Good luck!
