Re: Files required to use Windows Update are no longer registered or .

Are *any* updates for MSXML 3 showing in Add/Remove Programs in Control Panel ?

All are successfully registered EXCEPT msxml3.dll.

It appears that the issue is directly related to MSXML 3 not being present/or not functioning due to any number of factors.
Let's see if we can get the latest version of the MSXML 3 parser installed. Download and SAVE *msxml3.msi* from here:
http://www.microsoft.com/downloads/details.aspx?FamilyID=28494391-052b-42ff-9674-f752bdca9582&DisplayLang=en

Close all programs and browsers.
Show hidden files, folders, and system files:

Go to Start > Run > type in the below into the Open: line

cmd
Click OK or press Enter
At the prompt, type in the below *pressing Enter* after each command

net stop wuauserv
regsvr32 /u msxml3.dll
exit

Whether the command to unregister the msxml3.dll is successful or not, at this point in time the Automatic Update service is now stopped.
Using Windows Explorer, navigate to
WINDOWS\system32
Delete msxml3.dll by moving it to the Recycle Bin for now

Navigate to
WINDOWS\system32\dllcache
Delete the copy of msxml3.dll by moving it to the Recycle Bin for now
Close Windows Explorer

*Right* click the copy of msxml3.msi downloaded previously and choose Install.
Restart the system after the installation finishes.

Now try to access Windows Update. If access fails, please post the last 30 to 40 lines of the WindowsUpdate.log located in the WINDOWS directory [folder] and tell us which Antivirus/security software is installed ?

I am running a legal Windows XP SP2 on an Acer laptop. As far as I can remember, I was getting updates until a few months ago, but cannot remember seeing any recently.

I just went to Windows Update and got this message:

"Files required to use Windows Update are no longer registered or installed on your computer".

I click on the recommended "register or reinstall" option and all appears to work and then I get back to the Welcome to Windows Update page, and get the same error message again.

This happens for as many times as I click on the "register or reinstall" botton.

I have searched this forum and have tried many fixes:

1. I have tried running "regsvr32" and re-registering the following .dll's:
wuapi
wups
wuaueng
wucltui
atl
msxml3

All are successfully registered EXCEPT msxml3.dll.

2. I have downloaded and run WindowsUpdateAgent20-x86.exe. It appears to complete successfully but does not fix the problem.

3. I have downloaded and run WindowsUpdateAgent30-x86.exe. It appears to complete successfully but it too does not fix the problem.

4. I have tried 2. and 3. above with the /wuforce switch. It does not fix the problem.

Please can someone suggest another fix to try.

Thanks for any suggestions.
