When first attempted to install the update for KB3079777 it just says it failed. I went to trouble shooter and attempted to use that to fix the problem, but everytime it says it "fixed" an issue, the update would still fail, and I would go back to troubleshooter to run it again, and the same problems would pop up and it would again say "fixed." i've tried restarting my computer after the troubleshooter. Now the update is stuck at 5%. I had other updates to install as well and those worked, i installed each 1 by 1 until i got to the one that was not installing, which is a security update for internet explorer flash player.
