Thanks Jeff - I had created a Creative Cloud packager using the IT tool listed under the admin page for CC team.
When digging into the folder and launching the setup.exe it runs unattended, however as I mentioned 5 min into the install explorer exits and I am unable to see errors. It does not restart itself.
in the event log for this machine I see an error under application - Application or service "Windows Explorer" could not be restarted. event ID 10007.
just prior to that I see where it exits explorer as you mentioned. - Shutting down application or service "Windows Explorer".
