Update: I was able to get back up and running with the Authoring tool by updating the path in System Variables (C:\Program Files\adapt_authoring; C:\Program Files\nodejs).

I double checked the other paths, both global and local (see below). Is there anything else I need to correct? Also, is there a way to set up the FFmpeg app as I'm currently configured? 

Thx.

Jim
