Ok its fixed thanks to this post.
Me as well.
Tried system restore, didnt work. Tried uninstalling the updates and disabling windows update for 35 days since you cannot turn it off anymore. Rebooted tried to restart PLEX, NADA…
Any help on this?
Found it and it worked
If you upgraded Windows and you run into this problem, just look for the windows.old directory, go to syswow64, copy the mfplat.dll file from there and paste it into the c:\windows\syswow64 directory.
