Dominic,
That made the install work!
But on launch, Acrobat prompted for a user login. The instructions here: Creative Cloud Help | Deploying Adobe Acrobat mentioned that I should not put our CC license key in the wizard so I was not able to use the "Grant Offline Exceptions..." option. Putting the CC license key in the Wizard gives me a "[license-key-string] Error"], so I believe that's correct.
I do have my ccp file at the root directory of the package and that did seem to suppress the login request if I didn't reference the mst with a TRANSFORMS= paraemter. Is there a way I can make the msi aware of the ccp? I didn't see that in the available properties in the document you referenced.
Many, many thanks!
Ric
