This update seems to have been offered back in June. I suppose it has been having problems since then.
But it appears the install cannot create a package due to "error 800b0100 No signature was present in the subject".
I am not an expert at reading these things, so I might be on the wrong track, but it appears the package already downloaded is not, for some reason, useable. So I might suggest some things.
Do a manual check for available updates. That might get the system to verify some settings.
If the update shows as being installed, you might try to uninstall it.
If you have not tried a manual install, you can download the KB from here, and use IE.

If a manual install does not work, and you show the following file in its current directory, you might try deleting it.
C:\Windows\SoftwareDistribution\Download\de2b552d1042bd6ffeb054ce4588e824
If none of that works, the big hammer seems to be renaming or deleting the
SoftwareDistribution folder in the C:\Windows directory. If you do this, and I have, it will take some time for your system to catch up.
Your other updates appear to be working fine, so that would seem to confirm there is some problem with just this one.
