Are you getting an error message like below when trying to save a video in Screencast-o-matic while on a Windows computer on MPC's campus?

The problem is a missing file in the screencast-o-matic folder.  MPC's IT department figured out a solution:

  1. Windows Key + R  (That means, simultaneously press the Windows key and the R key. What's the Windows key?)
  2. In the Open text box copy & paste this line:
    xcopy \\ourgang\Screencast-O-Matic\libopenh264.dll %LocalAppData%\Screencast-O-Matic-v2\som-native-ffmpeg-win32-0.5\

  3.  Click OK.
  4. Try saving in screencast-o-matic again.
