If you are getting this error message when trying to open video files rather than image files etc, it’s a good idea to uninstall your graphics drivers using DDU Display Driver Uninstaller. DDU removes everything from your computer in a single process.
- To begin, make sure you have downloaded the latest graphics drivers from your computer or graphics card manufacturer's website (the support page). You can find the NVIDIA catalogue here. And the AMD catalogue is here.
- Now that you have done this, turn off your Internet connection and run DDU. Make sure that you enable the tick box next to Remove GeForce Experience when it appears. If you are using AMD graphics remove the Radeon software.
- Finally, restart your computer and install the driver software you downloaded earlier, then enable your Internet connection again. This will ensure that Windows doesn’t try to install a generic driver in the background instead of the official one.
After your drivers have been installed successfully, you should be able to open and use any media files without getting error 0xc00d6d6f again.
