Our learners do not have admin rights on the domain and the trainers don't really want to go round every pc putting their credentials in. Is there a setting in the mms.cfg which will allow adobe to automatically install silently WITH admin rights? or does SilentAutoUpdateEnable=1 not require an admin user/pass?
The automated background update does not require administrator rights; see http://forums.adobe.com/thread/981567
Major version upgrades (e.g. 11.x to 12.x) still need admin rights.
