Mass Effect 3 wont launch
as the title says, Mass Effect 3 wont launch on windows 10, it does however seem to launch in the background. I did a search for this problem and people were getting this error back in 2012 or whe...
Did you do a clean install of the game after Windows 10, or was it installed on a old version of windows originally?
Windows 10 is a bit more iffy on access level, and if say Mass Effect 3 was installed as an Admin back in the days, and now is trying to be run by Origin who is not an Admin, it could be causing problems.
As a quick first step: Try marking the ME3.exe file as to always run as Admin, and see if it launches then.
Otherwise, try a full repair of the game from the option inside Origin. (This should repair both the base game, as well as all the DLC)
