SQL Server 2012 SP2 update failure I have been having failures to install SQL Server 2012 SP2 on a 2-node active\passive cluster. I have uploaded detail and summary logs for the latest run on the passive node here: 
https://www.dropbox.com/s/4tlmv3hmzvbb9l4/Log%20Files.7z?dl=0

Due to not being able to pinpoint the error I have tried the following:


rebooting and running the patching from the GUI and command line with and without pre-extracting the files.
I have also ensured cluster services and SQL role are on the same active node, and brought the Available Storage group online although it does not have any unassigned disks in.
I have also ensured all default directories are present on the shared disks, and checked the registry for any features which are pending an update. I did not find any as I had seen reference to these problems.
I have also tried using 2 different admin accounts to run the setup even though I could not see any evidence of this problem


The GUI mimics the detail log showing all verification successful, the patching start; whereby after the patching begins it then ends with no error message. A completely blank feature list box is shown and a blank text box for log file locations, although these are obviously generated in the default location.

It seems to me the patching starts, but fails before any features begin to update without a specific error.

Any guidance is greatly appreciated.
Figured out the problem last weekend. After trying to run a repair on my SQL Server 2012, it reported that the user Administrator doesn't have the proper privileges in order to proceed with the installation, so I had to do the following:

Provide Full Control through Group Policy Management Editor in Computer configurations -> Policies -> Windows Settings -> Security Settings -> Local Policies -> User Rights Assignment to:


Back Up files and directories
Debug programs
Manage auditing and security log
