I cannot apply updates to Acrobat DC Standard version 2015.006.30033 32-bit on Windows 7 Enterprise x64. I have tried using the inbuilt updater and individually applying .msp's, running from an administrator command prompt. Each time I attempt to update DC it comes up with the error 28000 "Installation of Acrobat Licensing Module has failed. For potential workarounds to this problem please refer to http://www.adobe.com/go/acrobat_installation_rollback". The weblink details a fix for Acrobat X and XI however I have checked the registry entries, they are correct.
I can update exactly the same version of DC on Windows 8,1 Enterprise x64, don't even have to run from an administrator cmd prompt, does anyone know if there is either a pre-requisite required for Windows 7 x64 or another setting registry or otherwise I am missing to enable updates to be installed, many thanks.

Time to answer my own question, played with the UAC slider today. UAC in Windows 7 was set to minimum, when I set it to default I could install updates. Strangely Windows 8 has UAC set to maximum, makes no difference re. installing patches on 8.
