I tried installing this game on a fresh build, and it does not open. Uninstalled and reinstalled to no avail. Tried to run from both steam and ubisoft launcher and both give me the same issue. When i launch is says running on steam but does nothing but slow down my pc and i can barely more my cursor and have to restart my system. Does anyone have a solution for this? Any help would be appreciated not looking to play online, im fine with just marathon.
