The mf.dll file is one of many DLL files associated with Windows media player.
We have found that in order to record videos properly, Windows has to have this DLL in the system.
Since Windows N doesn't come with Windows Media Player as a default player, it doesn't include this file.
Don't worry though, we got you covered!
You can get the missing DLL files by downloading a Microsoft official Media Pack for your Windows OS:
- Media pack for Windows 7
- Media pack for Windows 8.1
- Media pack for Windows 10/ WIndows 10 (Build 1703)
