Re: sims 4 won't launch
@adancingirl Please move your entire Sims 4 folder out of Documents\Electronic Arts and onto your desktop. When you launch the game, if it launches, a clean folder will spawn with no content. Don't add anything to it yet; just see whether you can get far enough to start a new save and play in live mode for a bit.
If you still can't open the game, please run a dxdiag and attach it to a post.

Please also let me know what antivirus, if any, you use.
