I downloaded Medieval 2 Total war, and it is giving me a response like do you want to allow the following program an unknown publisher to make changes to this computer. And then there are three categories: program name: medieval2.exe, publisher: Unknown, File origin: Hard drive on this computer. It gives me the run around. I clicked Yes waited nothing occurs and I clicked No, because I ran out of choice, again nothing occurs. I need help any advice will be GREATLY!! appreciated. Thank you.
