Really EA? So after a long time, I decide to buy a game. pay 60 bucks for bf4, and when I go to launch it, and error code that says missing dxgi.dl pops up. Had this game for more than two weeks now, and havent been able to play at all. I even contacted customer support many times, but they can help me either. What I have done: 

Upgraded directx 

reinstalled the game 

reinstalled orgin 

Tried a new antivirus (Custommer support guys advice) 

I found the dxgi.dll file in system 32, so it is not missing.  here are my computors specs i found recently
