Blender 2.79 to unity 5.6 to animate character

I want to do this, https://www.youtube.com/watch?v=YTGYFA0GQwo But I am using blender 2.79 and unity version 5.6. How do I do it? Both are plain versions. With rigify already added on to blender. I meant unity 5.6.3. Anything could help, Any and all responses are welcome

I tried drop and dropping the fbx export file into unity and got this error :

GetObject failed to find Object for Library Representation UnityEditor.DockArea:OnGUI()

Anyone know what it is and how to fix it?

Not sure if this is important now since it seems an old thread, but maybe useful for future searches but this error message:
“GetObject failed to find Object for Library Representation UnityEditor.DockArea:OnGUI()”
is a Unity problem mostly related to the UI of the Editor, maybe trying newer Unity versions can help.
