Windows 10 / 64bit.

I got it up and running twice by uninstalling Knossos, then deleting everything I could find out of appdata\roaming and local and everywhere.

Now I have 2 tabs on Knossos front screen - retail and The Babylon Project which I installed. Media MVPs are in the 'install' tab now even though they weren't for the first run runs. installing them gave me trouble before; perhaps I should now since the game stopped running.

The retail icon on the home screen executed 19.0.0.0 twice as I mentioned but now just flashes with nothing running.
