I had this same problem. I found that the problem was that I disabled the
"Office Source Engine" service. I re-enabled and started the service
according to the instructions in the office help file: C:\Program Files
(x86)\Microsoft Office\OFFICE11\1033\SETUP.CHM )
After restarting the service, I ran Windows Update and it once again failed
to install the updates, so I downloaded the "manual" install files for each
of these updates from
http://download.microsoft.com (I found them by
searching for the "kb" number of each update). The manual installers worked
fine, and my system is now up to date.
Hope this helps!
