I tried everything removed virus protection, tried starting from program files
Steam : // rungameid/522470 still wont down load or launch.I also unstalled and reinstalled into a different drive. I guess I will have to ask for my money back
Asking for your money back is probably easiest -- especially since they aren't giving you any tech support.
But looking at that
Steam : // rungameid/522470
business makes me think it has similar issue as thishttps://steamcommunity.com/app/214190/discussions/0/616188677660212061/
You may have to run the game through Steam, instead of using a desktop shortcut -- or at least making sure Steam is running before attempting to start the game with the shortcut.
The "rungameid" problem does find answers on Google that aren't specifically related to "House of Da Vinci" but to any games using Steam DRM.
