It appears that every time I ran Obduction, it tried to install the C++ 2015 Redist. I'm on Windows 10 and I have the C++ 2015-2019 redist installed. I could not find anything in the Event Log related to this. There was no message from Obduction that indicated a problem. This created so many system restore points that it nearly ran my system drive out of free space. I finished the game, but I may like to go back and figure out a few things. I have uninstalled it and deleted everything at this point. The game ran fine, BTW. It's just the restore point issue. I'm not inclined to change my system just for this game.
