KB977816 keeps notifying

I have a W2K server with auto update setup.

The thing is that, few days ago it downloaded a bunch of updates, including
KB977816 and installed all of them. It is however, according to "add/remove
programs", the KB977816 has been installed, but auto update keeps notifying
that the update is ready to install. When ever I let auto update installs it,
it just shows update was successful, no error. But less then a minute later,
the auto update notify the KB977816 is ready for install again.

Tried restart many times, did not help, tried stopping auto update service
and starting it again, did not help....

I know it's already installed, and I just want to get rid of that auto
update notification coz it's really annoying....
Any ideas?

See the "How to obtain help" section of

Just out of curiosity, what service pack are you running?

RE: KB977816 keeps notifying

I'm running service pack 4, basically all critical updates are up to
current, except this KB977816 issue is rather irritating.

I also tried to enable install mode by putting the command "change user
/install" in the command prompt, didn't help either.

Nevertheless, I tried to do it manually by visiting the windows update
website, again, it said update successful... no errors had happened.... I
even tried to install it manually by downloading the patch from MS and
install it with install mode... again... the installer claims that update is
successful and that the patch also successfully recorded in the "add/remove

I check also the log... also told that the update went successful.

Really have no idea what went wrong

If you review the names / dates of the files updated by the patch, most
likely you will find that one or both did not get updated properly.

From TechNet Article:
'MS10-026: Vulnerability in Microsoft MPEG Layer-3 codec could
allow remote code execution' (http://support.microsoft.com/kb/977816)
Windows 2000 file information
For all supported editions of Microsoft Windows 2000 Service Pack 4

Date Time Platform
L3codecx.ax 143,422 21-Jan-2010 19:46 Not Applicable
L3codeca.acm 307,260 21-Jan-2010 19:48 Not Applicable

On the few machines that I was seeing this issue on, L3codeca.acm, in
%WINDIR%\System32 was not updated, even though the patch reported as
successfully installed.

Suggestion would be to manually copy L3codeca.acm from a different
machine and replace on the problem machine.

This process resolved the issue for me.

I am having the same problem but I do not have another machine to copy
L3codeca.acm. Any other way to fix this?

Windows Update extracts the files that are part of the patch here:
%WINDIR%\SoftwareDistribution\Download\{long series of numbers an
letters}\{Sub Folders} (Don't have exact folder name for this patch)

Search for "L3codeca.acm" there

Install Media Player Nine and its subsequent updates. 977816 will then
detect correctly. I bet this issue only is occuring with machines still at
media player version 6.4.

I did exactly what you suggested. It cleared the annoying problem.
Although in my case the l3codecx.ax was not updated aoutomatically.
