Thats really weird, thats somenthing that only happens to you. The game was made in unity and the export is a .exe application but it doesnt need another program to open it its really weird and it should not be required im very sorry to hear that you cant try it. I suppose that you have winrar to decompress it before, otherwise the .exe won't appear. If you need help about decompressing tell me I can guide you but if it isnt the case im very sorry that I cant help more
