Going back to step one, if you did not install DirectX download software then you will need to go into the control panel. Usually, the most recent driver’s version is listed first. The more specific version number will always be found when you have the program running.
The DXVA_RUNTIME_VERY_MEDIA_ROM_DLL error should be listed as one of the two followings: enabled or disabled. To check what specific version you have, press Alt+F2 and type in the following: “DXVA_RUNTIME_VERY_MEDIA_ROM_DLL” (minus the quote marks). If you experience this problem then the chances are that you do not have the correct DirectX runtime library installed on your system. The DirectX runtime library is what allows the computer to communicate with the DirectX drivers. This can be very scary because many people do not realize that this is an issue with the DirectX runtime library. That’s fine, but you might encounter something like “DirectX Runtime library not found”. When you first download the game, it will usually prompt you to select a driver.
