OMG, I tried both the app, and installing it by hand. As for error messages it saying I needed "Microsoft Visual C++ 2015" which it installed but refused to recognize it's own work. I checked and it's installed. So where it stands is I have Microsoft Visual C++ 2015, Aven Colony insist I don't, and refuses to run. The "app" supposedly "installed" the game, but it's the same story, it can't find Microsoft Visual C++ 2015. Not much I can do if the software can't deal with reality.
Why did I format my disk? Answer: Microsoft Windows operating system, needs to be nuked on a regular basis.
