@carromedc Are you still getting the same error? If so, please do a clean uninstall and reinstall of both Origin and Sims 4. Start by uninstalling Sims 4:
- If there's a Sims 4 folder in Documents\Electronic Arts, put it aside and rename it to something that doesn't include the words "Sims 4."
- Download Revo Uninstaller (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.
Next, uninstall Origin:
- First, clear Origin's cache.
- Quit Origin, then right-click on the Task Bar and open the Task Manager. Scroll through looking for Origin entries. If you find any, click on them and End Task.
- Launch Revo again and uninstall Origin, and when it's uninstalled, select "Moderate" again and Scan.
- If Revo finds any remaining registry entries, select all, delete, and click Next.
- Revo will display "Remaining Data and Folders. Select all of them, except exclude the "Origin Games" folder if you have other Origin games installed. Delete the rest.
- Close Revo, and restart your computer.
Next, download the full Origin installer and run it. Here's the direct download link:
http://download.dm.origin.com/origin/live/OriginSetup.exe
Be sure to run both the installer and Origin itself as an admin: right-click on each and select "Run as Administrator." Install Sims 4, but don't put the old Sims 4 folder back in Documents\Electronic Arts yet. Just see whether you can play at all.
