I just tried packaging MUSE again today. After the install I still get prompted for an Adobe ID. After contacting our Adobe Education people they gave me this website:
http://helpx.adobe.com/creative-cloud/packager/installing-products-exception-folder.html
If you read a section towards the bottom is says:
To supress the Sign in screen, run the following command. This step is not applicable in the case of named licenses.
- adobe_prtk --tool=Register --leid=V7{}Muse-80-Win-GM --regsuppress=ss
Hope this helps everyone. Still frustrating!
