This might not work in your case, but it worked in mine.
I have a Razer keyboard and run Synapse software ... for me, it was stopping the game from launching ... but I didn't know that. A week with EA tech support to figure that out. If I shut down Synapse (or Razer Comms ... which I don't have) the game seems to launch just fine. Once the game launches, I can start up Synapse and everything works fine.
It seems that for whatever reason, Synapse prevents "activation UI (32 bit).exe" from doing its thing ... but once the UI closes out, Synapse can run with the DAI executable with no issues. I've also up channeled this to Razer as a bug.
Obviously, if you are not running Synapse or Razer Comms ... then this is not your issue ... but I hope this can help someone avoid all the wasted time I went through, getting the game to work.
