Sims 4 Error Code [0e6d1221:1df4e8dc:0000012d:912c9c10

@cicimarie08  Is this the driver you tried to install?

If you're not sure, try running it now.  Right-click the download and select "Run as administrator," choose the Custom (not Express) install method, and check the box to perform a clean install.  Restart your computer when it's done.

If you can't install that driver, 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, 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, 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.

Then try again to install the driver.  If that doesn't work either, clean-uninstall the old driver, as described here:

and try the new driver one more time.

Thank you so much! I think I figured it out and it was my gshade mod. But I will keep this information handy. Thanks again!

hello i just wanted to ask if you were able to play with gshade still because i have the same problem and it also opened when i uninstalled gshade but i cant play without it☹️

@jo_yulz  Gshade doesn't work well with Sims 4 anymore.  Try Reshade or another tool like it instead.
