It turns out that for some reason the provisioning process is not capturing HKLM\SOFTWARE\Policies\Adobe branch of the registry. Any thoughts?
I believe that the entire HKLM\SOFTWARE\Policies is being excluded from the appstack mostly due to some strange behaviour with Windows policies which are in the exact same place as the Adobe ones.
We had an issue way back where these settings were stored in the writable and we needed to recreate writables to get policies to be upgraded after changing them. I believe that this is teh reason they took it out. You could try and change it within the snapvol.cfg of the Adobe CC appstack.
We had some specific Adobe DC settings that we needed and eventually import the admx file for adobe_dc into our the active directory domain, that we use for the microsoft windows VDI sessions and made group policy that made the setting. That seemed to work everytime.
