Re: The sims 4 64 bit won't load due to missing core/activation64.dll

@Chuu_0rbit  I've split your post into its own thread since the other thread was a bit old, and I don't want it getting closed before you've been helped.

First of all, please post the exact error message, for reference.  Please also let me know what antivirus you use, if any, and what game client you used to install Sims 4: Origin, the EA App, or Steam.

I'm also having the same issue as this guy and I don't use an antivirus. Any luck?

@leoetralip  Please run a dxdiag and attach it to a post.

here you go.

@leoetralip  Just to be sure, you're seeing exactly the same error as is in the thread title?  If not, please post a screenshot of the error.

Either way, please also run a couple of basic checks of your Windows system files.  Here's how:

• 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.

Clear the EA App's cache:

Then uninstall the App, restart your computer, download a fresh copy of the App's installer, and run it.  Repair Sims 4: open your game library, click Sims 4, and select Manage > Repair.  Try again to play, with nothing else running on your computer, and let me know what happens.

Okay, I tried all the steps, still nothing. But I will send the screenshots.

@leoetralip  Please try running Origin and Sims 4 as an admin: right-click on each desktop shortcut, or TS4_x64.exe if you don't have a shortcut for Sims 4, and select "Run as administrator."

If that doesn't help, have you tried uninstalling Sims 4 yet?  The original poster did, but if you haven't, that would be the next step.  When reinstalling, create a different folder on the root level of the C drive, for example C:\Games is fine, but not C:\Program Files\Games.  When the EA App asks you where to install Sims 4, choose that folder.

I ran the EA app as admin, the sims wouldn't let me set it as admin, TS4_x64.exe when i pressed "Set as Administrator", it just showed the error. I also uninstalled and reinstalled the Sims 4 too.

@leoetralip  Please try playing in a clean boot:

The one service to leave enabled is the EABackgroundService, which the EA App needs in order to run.  Disable the rest as described.

When you reboot your computer, go through the Task Manager's background processes list shutting down any service that doesn't absolutely need to be running, for example anything from MSI Afterburner to RGB software might still be enabled.  If you accidentally kill a critical process and it doesn't restart on its own, just reboot your computer again.

I just tried that, sadly still nothing. Same error.
