KB885836 & KB885884 - Installation Failed

This past week, Windows Update surprised me with 2 security Hot Fixes -
KB885836 & KB885884. Update proceeded well, downloaded OK, but the
installation of both Failed. (Note that these Hot Fixes appear to be older,
had been originally installed some time ago, and the $NtUninstall folders for
both deleted since then)

I then manually downloaded each Hotfix and tried running the individual
installers, after deleting what the Windows Update had downloaded, only to
receive the follow error messages (same messages received when I tried again
in safe mode):

KB885836 Setup Error
HKLM\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Hotfix\KB885836
to file C:\Windows\$NtUninstallKB885836$\reg00001. 5: Access is denied.

Similar Setup Error message with KB885884.


** Any assistance in trying to solve the installation issues for these 2 Hot
Fixes would be GREATLY appreciated!

Thank you!
