If you’ve encountered the error message “Could not load file or assembly ‘MOM.Implementation'” on your Windows 7, 8, or 10 computer, you’re not alone. This frustrating issue often appears when booting the computer or launching software that depends on AMD graphics drivers. Fortunately, this error is not as ominous as it sounds and can be resolved through a few simple troubleshooting steps.
Let’s walk through what this error means and how you can fix it effectively, regardless of your Windows version.
What is MOM.Implementation?
The MOM.Implementation file is a component of AMD’s Catalyst Control Center (CCC), which is used to control and configure AMD graphics hardware. This program relies on .NET Framework and other underlying assemblies to function properly. When something related to these components is missing or misconfigured, Windows throws the error.
Common Reasons for the Error
- Corrupt or incomplete AMD Catalyst driver installation
- Conflicts due to a Windows update
- Missing or corrupt .NET Framework files
- Traces of previous graphics drivers causing conflicts
With these causes in mind, here are several proven methods to fix the issue.
1. Reinstall AMD Catalyst Control Center
Since MOM.Implementation is managed by the Catalyst software, reinstalling it often resolves the error.
- Press Win + R, type appwiz.cpl, and press Enter.
- Find AMD Catalyst Install Manager, right-click it, and select Uninstall.
- Follow the prompts to remove all AMD software components.
- Restart your computer.
- Visit the official AMD website, download the latest Catalyst Control Center or Adrenalin software, and install it.
This fresh install removes any corrupted files and ensures the missing components are restored.
2. Update or Reinstall the Graphics Drivers
This issue may stem from outdated or broken display drivers.
- Open Device Manager by right-clicking the Start button and selecting it.
- Expand Display adapters, right-click your AMD device, and choose Uninstall device.
- Check the box for Delete the driver software for this device, then click Uninstall.
- After rebooting, visit AMD’s website and download the most recent driver for your specific graphics model.
- Install the driver and restart your computer.
This process ensures you’re using the correct and latest drivers, which often correct any misaligned assemblies like MOM.Implementation.
3. Repair or Reinstall the .NET Framework
Because MOM.Implementation relies on .NET Framework, a corrupted framework installation could be the root of the problem.
Here’s how to repair it:
- Press Win + R, type appwiz.cpl, press Enter.
- On the left, click Turn Windows features on or off.
- Uncheck any versions of .NET Framework listed, click OK, and restart your PC.
- Go back and re-check the boxes to turn the features back on.
If this doesn’t help, download the .NET Framework Repair Tool from Microsoft to automatically detect and fix problems.
4. Clean Old Drivers with DDU (Display Driver Uninstaller)
Stubborn remnants from old driver installations can conflict with current software.
- Download DDU from its official page.
- Boot your system into Safe Mode.
- Run DDU and select the option to completely remove AMD drivers.
- Restart and install the latest drivers again from AMD’s site.
Many users report that using DDU clears out anything left behind that could be causing the MOM.Implementation error.
5. Disable Catalyst Control Center from Startup (Optional)
If you do not use Catalyst Control Center features, disabling it from auto-start can suppress the error.
- Press Ctrl + Shift + Esc to open Task Manager.
- Click on the Startup tab.
- Find Catalyst Control Center, right-click it, and choose Disable.
This won’t fix the root problem but can prevent it from popping up every boot.
Final Thoughts
The “Could not load file or assembly MOM.Implementation” error can seem intimidating, but in most cases, it’s simply a driver or software mismatch. By following the solutions above, you can eliminate the issue and enjoy a fully functional system again.
If none of these methods work, consider reaching out to AMD’s support team or using Microsoft’s community forums where similar issues are often discussed and resolved by experts.
