Update Rollup For SQL Server Service Pack 1 Failed (KB2793634) Code 84BC0791

I had a difficult time finding the pertinent information for resolving this issue.  You can find the appropriate Knowledge Base article at this link: http://support.microsoft.com/kb/2793634

Basically there are two instances of this sql server 2012 update error and they can both be found in the above link.  Resolution is also available in that article.
