Hello,
I repaired, uninstalled and reinstalled vcredist* files version 14.0.24212 without any progress.
I uninstalled Origin, downloaded Origin Legacy and it worked but not for the game installed (DA:I)
Then I installed the latest Universal C Runtime from Windows, but no result... the game keeps crashing :-(
(Windows 8.1)
... then i noticed I had a Windows update as well as the Origin update, so I rolled back the Windows update... the game keeps crashing...
......Then.... I cried !
Then... I spent useless time with EA support, and looking at the forums I made an antivirus exception for DAI and it worked. For a reason I don't know, using the Legacy edition or updating Windows provoked a regression with the antivirus.
So now I know the las version of Origins contains a bug with some versions of Windows (7 and 8 it seems) which it not solved, and i'll have to be careful not to update Origin in the future...
