Going around in corcles with Windows Update

Hi --

I have a Windows XP Pro SP3 computer that cannot complete a trip to Windows
Update.

I open Windows Update and click on the Custom button. WU stops abruptly at a
page with the error "Files required to use Windows Update are no longer
registered or installed on this computer."

If I select the default option of the two given ("Register or reinstall the
files for me now") and click Continue, WU supposedly downloads and registers
the missing DLLs (I get a "Registering:" with a percentage count that goes
to 100%) and takes me back to the Welcome to Windows Update page.

When I click on the Custom button, I wind up back at the page with the
"Files required to use Windows Update are no longer registered or installed
on this computer" error.

This time, I select the second option ("Let me read about more steps that
might be required to solve the problem"). I'm taken to a search page with
two links referencing a 0x800A01AD error. (Note that this error is mentioned
only on this search page; the page I came from shows no hex error code at
all.)

The first link has instructions to reregister a mess of DLLs -- MSXML3.DLL
and the 7 WU DLLs. I reregister them all without a hitch.

When I go back to Windows Update and click on Custom, I wind up back at that
"Files required to use Windows Update are no longer registered or installed
on this computer" error.

The second link on the "Let me read more about ..." page details steps to
ensure that the Windows Update registry entries have the proper permissions.
I checked; the permissions are correct.

But I can't run Windows Update. I repeatedly wind up at that "Files required
to use Windows Update are no longer registered or installed on this
computer" page.

How do I fix this?

Thanks,
CL

One assumes you've tried the recommendations here:
http://support.microsoft.com/default.aspx/kb/833766

Is this a sudden, new problem or an ongoing one?

Did you just reinstall WinXP and install SP3 manually?

Is Automatic Updates enabled (cf. ttp://support.microsoft.com/kb/306525)?

What anti-virus application or security suite is installed and is your
subscription current? What anti-spyware applications (other than Defender)?
What third-party firewall (if any)? Has a Norton or McAfee application ever
been installed?

If you reboot into Safe Mode with Networking & then visit
http://windowsupdate.microsoft.com, does the behavior persist? [CAREFUL!!
Only remain in Safe Mode w/Networking long enough to check this behavior!]

This PC has MSXML SP7 installed (and verified).

I don't know exactly how sudden it is, since this PC has Automatic Updates
enabled and is supposedly keeping up with them. I went to WU to check on a
driver update, and to see what else there was to apply. AFAIK, this PC
hasn't visited Windows Update in at least a month, if not longer.

An SFC fix and a reapplication of SP3 were performed on this PC several
weeks ago to correct a problem of a user poking atround where he shouldn't
have been ...

Yes.

Symantec Endpoint Protection v11 under control of the SBS server on this
domain. Recently upgraded from Symantec AV Corp v10.

I followed every step listed there and in the several KB articles that
thread referenced. I even reinstalled the Windows Update agent, which led to
a surreal situation:

1) I installed the (supposedly latest) Windows Update Agent from the Windows
Download site.

2) I rebooted the PC.

3) When I hit Windows Update, I was informed that the Windows Update
software needed to be updated.

4) The PC downloaded and installed the newest WU code.

5) I wound up at the page with the "Files required to use Windows Update are
no longer registered or installed
on this computer" error.

WTF ...?

I'm getting dizzy from all these circles I'm going in ...

Hi Charles, I note nothing appears to be helping you at this stage -

Clear out all the TIF etc and then perhaps try this (just in case there's a
bad cookie or something there) can't hurt:

Then see:
http://support.microsoft.com/kb/326253
Method 5: Register Windows Update engine files

You may have to reboot (sometimes that helps for some reason).

I agree with TauArian's suggestion to clear the TIF.
However, that wouldn't change Cookies at all.
(FYI the Cookies you see in the TIF Viewer are only seen there
because the TIF Viewer combines the viewing of both the
files in the TIF and the files in the Cookies folder.)

Depending on your version of IE an adequate alternative
to that procedure might be to just press Ctrl-F5
while you are viewing what may be only a bogus message.
(FYI Ctrl-F5 originally issued requests for all components
of a page as if there was no previously cached file associated
with it. Lately, it seems it only does that partially at best.
Hence to see the effect of doing a refresh with all new files
unfortunately it may be necessary to clear the TIF completely.)

Time for some diagnosis? <eg>

<title>How to read the Windowsupdate.log file</title>
http://support.microsoft.com/kb/902093

Note that you could optionally invoke verbose logging
using the instructions given in that article and retry
to get even more clues. Even better IMO would be
to retry while running ProcMon and use it to supplement
whatever messages you do get from any other diagnostics.

Also, I suspect, there might be some additional clues
in the Event log which could either clarify or negate
the implications of the messages you are getting.


Good luck
