Let us see these in detail.

1] Restart your PC

If the DLL issue is temporary, a simple restart might fix the problem.

Right-click on the Start button icon to open the WinX menu. Then select Shut down or sign out > Restart.

2] Check the file location

Once the DLL is installed on your Windows 11/10 PC by a program, it should remain in the program installation folder, along with the launcher (.exe file). If you’ve accidentally deleted the file, recover it from the Recycle Bin. If you’ve unintentionally moved it elsewhere, keep it back in the program’s installation directory. After this, the program should run without any errors.

3] Update graphics drivers

The error may also occur due to outdated graphics drivers. Use Windows Updates to update your graphics drivers and fix the issue.

1. Type ‘updates’ in the Windows Search bar.
2. Press the Enter key.
3. Click on the Check for updates button.
4. Install the available updates.
5. Reboot the PC and see if the error is gone.

Note: Apparently, the DLL is from NVIDIA CUDA runtime and is shipped as part of the NVIDIAPhysX Runtime. The error could be fixed by installing the nVidia PhysX drivers or the stand-alone CUDA drivers, which are available on nVidia’s website.

4] Reinstall the problematic app

If the DLL was included in a program but got corrupted, reinstall the program to fix the issue.

1. Press the Windows key on your keyboard.
2. Select Settings.
3. Go to Apps > Installed apps.
4. Search for the app.
5. Click on the three dots icon next to the app’s name.

6] Perform a System Restore

If you’ve created a system restore point prior to the occurrence of the issue, you can perform a system restore to get the program back to its normal working.

1. Press the Win+R keys to open the Run dialogue box.
2. Type rstrui.exe in the Open field and press the Enter key. This will open the System Restore dialogue box.
3. Click on the Next button to see all available restore points.
4. Select the point you created before the occurrence of the error.

6. Click on the Finish button to perform a system restore.

Note: If you’re thinking to download the missing DLL file, I would suggest you download it from the original distributor who creates the DLL as part of their software package. Most of the websites that allow individual DLL downloads are not ‘approved’ sources for downloading DLL files. So there are fair chances of the file being outdated or infected with a virus.

This is all about fixing the missing DivxDecoder.dll file error on a Windows 11/10 PC. I hope it helps.
