I didn't installed the EA Download Manager and I will not, there's enough useless programs in memory.
Please post a direct download link for the offline patch installer for the retail version of the game.
I'm tired to search all the Internet, this patch must be the first thing visible on the official site...

Thanks.

OK, found it deep in the forum (Thx to Sovereign27) :
