Windows 10: Device Manager not working - mmcbase.dll not found

I am unable to open device manager and get an error message reading:


"The code execution cannot proceed because mmcbase.DLL was not found. Reinstalling the program may fix this problem".


I ran a SFC to try and identify the error and have followed methods 1-3 in this: Fixed: Windows Resource Protection Could Not Perform the Requested Operation ubackup.com but the SFC stops at 13% before I get the message 'Windows Resource Protection could not perform the requested operation". I get the same result when running the SFC in safe mode.


I'd be grateful for advice on the device manager error message.

Hi Luke,

We suggest that you update the device driver. You can do that by following these steps:

• 
  Select the Start button, type Device Manager, and select
  it from the list of results.
  
• 
  Expand the category where your device is located, then right-click on the name of your device, and select Update Driver Software.
  
• 
  Select Search automatically for updated driver software.
  

If Windows doesn't find a new driver, you can try looking for one on the device manufacturer's website and follow their instructions.

If updating the device driver doesn't work, we suggest that you reinstall the driver:

• 
  Open Device Manager.
  
• 
  Right-click on the name of the device.
  
• 
  Select Uninstall.
  
• 
  Restart your PC and Windows will attempt to reinstall the driver.
  

Let us know how it goes.
