Error 803 Legacy Edition
- 6 years ago
@MonKind Your dxdiag lists a number of errors that are most likely related to your graphics card driver. Some of these list the 32-bit version of Sims 4; none list the 64-bit version. So it's not entirely clear that the problem with the 64-bit version is driver related, although it could be.
Since it's simpler, the first thing to try is to move your entire Sims 4 game folder out of Documents\Electronic Arts and onto your desktop. When you launch the game, if it launches, a clean folder will be created with no content. Don't add anything to this folder; just see whether you can start a new save and play for a bit. Let me know either way.
If that doesn't help, temporarily disable your antivirus/firewall, just long enough to see whether it helps. If it does, you can set exceptions for TS4_x64.exe and Origin.exe.
If the game still won't load properly, the next step would be to do a clean uninstall and reinstall of your graphics driver. First, download Display Driver Uninstaller from here:

You can download a fresh driver here:

Next, take your computer completely offline—disable wifi and/or pull the ethernet cord—and double-click the DDU.exe. Take note of where the file will land, and click Extract. If it's easier, you can copy the path and then paste it into the address bar in a File Explorer window. Open the folder and then Display Driver Uninstaller.exe, and you'll get a message that you're not in Safe Mode. Click OK, then go to Options and enable Safe Mode dialog. Here's a screenshot of what your options should look like; make sure the box in red is checked:
Close options, and the DDU, and then open the DDU.exe again. For launch options, choose "Safe Mode (Recommended)," and then click Reboot to Safe Mode (you'll need your password, so find it before rebooting). Once you login, you'll see this:
In the blue box, choose GPU, then Nvidia if it's not already showing. Then click Clean and Restart red box).
Once your computer has rebooted, now back in normal mode, run the driver install .exe in custom mode. Select "perform a clean installation" and install ONLY the GPU driver and the PHYSX software.
Reboot again and see whether you can launch the game. If not, let me know.
