I recently updated to windows 10 Pro N Insider Preview, build 18305. Now I cannot stream from Prime video, Dstv, BBC etc on Edge and Firefox. I am advised to install the media feature pack for N versions of Windows, however upon trying to install, I get the error "installation not valid for this version of Windows". I have double checked my windows version, OS type. I am using media pack version 1809 for x64 October release. Anyone here been able to successfully install the media pack?
