Re: Sims 3 wont launch from origin

@Alyschris  I've split your post into its own thread.  You didn't do anything "wrong," don't worry about that; it's just that the other thread is a collection of posts only about the DirectX 9 issue, and your dxdiag and the fact that you already installed DX9 show that your issue is different.

On that note, the errors in your dxdiag point to a problem with one of the .NET Frameworks, so the place to start is with repairing them.  First, please run a couple of basic checks of your Windows system files:

• Hit Windows key-X
• Choose either “PowerShell (Administrator)” or “Windows Terminal (Administrator),” whichever option is offered
• Inside the window that appears, copy and paste “DISM.exe /Online /Cleanup-image /Restorehealth” without quotes into the window, and enter
• The system will start validating soon. If it throws an error, please list it here
• After it reaches 100%, hit Windows key-X again
• Again, choose “PowerShell (Administrator)” or “Windows Terminal (Administrator)”
• Inside the window, copy and paste “sfc /scannow” without quotes into the window, and enter
• Post the message you receive here

Restart your computer, hit Windows key-i, select Update & Security, and click the box to check for updates.  If any install, restart again afterwards.

Next, hit Windows key-R, enter "appwiz.cpl" without quotes, click "Turn Windows features on or off," find .NET Framework 3.5 on the list (it should be right at the top), and click the filled-in box next to it to uninstall.  Restart your computer yet again, then repeat the process, except this time you'll click the now-empty box to reinstall, then restart.  If the box is already empty, you can simply install and restart.

If you still can't play after this, please post a new dxdiag.
