I fixed my problem. The issue was this:
Origin Games\The Sims 4\Game\Bin\Core\ActivationUI.exe
I just happened to see in my HIPS that it didn't recognize that file, so I whitelisted that file and the game launched. Hope it works for you too.
I paid over $80.00 for the sims4 for it not to work??? It is already installed and Origins is asking me to download the game and the code is on the screen; this is ridiculous!!
