A few of the updates, although they appear to download and install correctly, if you run a second scan at the Windows Update site, or if you check again on Automatic Updates, they popup again as if they need to be reinstalled. Here, there were three: KB2810048, KB2760588, and KB2760411, all for MS Office but on Windows XP AND Windows 7 computers.. A quick check of the internet shows that almost all folks are having the same issue on all relevant operating systems.. See the link below:

Running a few tests to see if I could fix the issue, I uninstalled the updates from a couple of computers, downloaded the offline installation files, then ran the installation offline.. I also uninstalled the offending updates but let the Windows Update site re-install the updates.. Nothing worked and as the discussion at the websites above suggest, it appears like the fault is Microsoft.. I'll guess they will fix the problem or re-release a "fixed" version of the update at a later time.
Hope this helps.
