Sims 4 wont launch EA app says its damaged or data is missing
@DarkTwistyDragon The error message is misleading and needs to be updated. For Windows users, the EA App is the only option available; Origin was retired months ago.
At any rate, please do a clean uninstall of Sims 4 with Revo Uninstaller:
- Put aside your Sims 4 folder in Documents\Electronic Arts and rename it to something that doesn't include the words "Sims 4."
- Download Revo (the free version is fine) from here.
- Launch Revo, select Sims 4 from the list, and click Uninstall.
- Once the game is uninstalled, select "Moderate" under "scanning modes," and click Scan.
- Review the list, in case there's something you want to save; otherwise, click Select All, and then Delete.
- Close Revo, and restart your computer.
Uninstall the EA App with Revo as well. I don't have instructions for that at the moment, but the process should be straightforward. Restart again when you're done.
Install the EA App, then create a new folder into which you'll install Sims 4. The folder should be on the root level of the drive of your choice, e.g. C:\Games is fine, but not C:\Program Files\Games. Install Sims 4 and see whether it launches. If you use a third-party antivirus, disable it before reinstalling the EA App, and don't reenable it until you've tried to launch Sims 4 at least once. As long as you don't do anything else at the same time, your computer should be safe.
If you still can't play, please run a dxdiag and attach it to a post.
