The windows update "Microsoft SQL Server 2012 Service Pack 3 (KB3072779)" kept failing when trying to install. I manually downloaded the service pack and installed it and it installed successfully but the update is still listed in windows update. When I try to run it anyway i get a 84B30002 error.
I have tried clearing out my windows update cache by renaming "%SystemRoot%\SoftwareDistribution" and "%SystemRoot%\WindowsUpdate.log" doing a "wuauclt /resetauthorization /detectnow" from the command line but it still is listed.
No entry gets created in C:\Program Files\Microsoft SQL Server\110\Setup Bootstrap\Log when the update tries to run from windows update.
Checking the event log I get the message "Installation Failure: Windows failed to install the following update with error 0x80070643: Microsoft SQL Server 2012 Service Pack 3 (KB3072779)."
