I uninstalled Origin and EA, try it again, downloaded EA from Steam and the game doesn't launch.

Why do you have EA and Origin at the same time? To install EA it uninstalls and replaces Origin

frigging hate the EA app. It makes my screen flicker like crazy

Because EA Desktop is replacing Origin on Steam, games are opening with the new app. All perfect with other titles like Burnout Paradise, but I have this problem with BF V, I open it from Steam and it opens EA Desktop but it doesn't open the game, I have to close it, and open Origin so that the game can start. Any way to fix this? that it opens Origin directly or that the game can open from EA Desktop. 

(EA Desktop doesn't show the game as installed.)

Steam opens EA Desktop, but it doesn't open the game, I have to open first Origin.
