cant start SIM4 in steam

Hi there, 

I'm sorry to hear you're having problems launching your game. There are a couple of things you can try to fix that. To start with, I suggest that you "Verify Integrity of Game Files". 

• Open Steam.
• Go to your Library, right-click The Sims 4, and select Properties.
• Under the Local Files tab, click Verify Integrity of Game Files.

If the problem persists, please try running Steam and the EA app as an admin, and also make sure that your Antivirus or Firewall is not blocking the game from running. 

Let us know if you have any questions.
