Windows Update problem - KB 927978

  gigis 17:59 15 Nov 2006

Hi there,

Windows updates was running normal untill today.

Today intalled the following updates (Nov. updates):
KB 890830 / 920213 / 923980 / 924270 / 922760 /
and xx KB927978 xxx.
The problem started after the installation of KB927978 update:

Upon visiting Windows Update or Microsoft Update again, I receive an error msg that states:

Files required to use Microsoft Update are no longer registered or installed on your computer. To continue:
Register or reinstall the files for me now (Recommended)
Let me read about more steps that might be required to solve the problem

So I click on Continue while using the Recommended setting, and after the
browser downloads and registers it's software automatically, it re-routes to
the same webpage to register or reinstall the files.

I am running Windows XP Home, IE 6 SP2.

Advice welcome

Are you able to go back and read the "Let me read about more steps that might be required to solve the problem" bit to see if it gives more clues. as you probably know that update was to fix an Active X vulnerability, specifically "A vulnerability exists in the XMLHTTP ActiveX control within Microsoft XML Core Services that could allow for remote code execution"

I had a problem with windows update today an eventually fixed it by:

"Renaming C:\windows\softwaredistribution\DataStore to C:\windows\softwaredistribution\DataStore.p and that will reset Microsoft Update.

Click Install Updates again and you should be back in business"

Found this fix in PCA archives credit to Fruit Bat /\0/\

Thanks to all who answered.

I found the following solution in Windows XP Newsgroups,credit to Anton Pegan.

Just re-register the Windows Update files manually:

- Start/Run, type cmd

net stop wuauserv

regsvr32 wuapi.dll /s

regsvr32 wups.dll /s

regsvr32 wuaueng.dll /s

regsvr32 wucltui.dll /s

regsvr32 wuweb.dll /s

regsvr32 msxml.dll /s

regsvr32 msxml2.dll /s

regsvr32 msxml3.dll /s

regsvr32 urlmon.dll /s

net start wuauserv

regsvr32 softpub.dll /s

regsvr32 initpki.dll /s

regsvr32 mssip32.dll /s

regsvr32 wintrust.dll /s

regsvr32 dssenh.dll /s

regsvr32 rsaenh.dll /s

regsvr32 gpkcsp.dll /s

regsvr32 sccbase.dll /s

regsvr32 slbcsp.dll /s

regsvr32 cryptdlg.dll /s

regsvr32 jscript.dll /s

Then restart your computer.

I had a simular problem and discovered my windows installer was disabled.

This solution may help:
go to START

Double click Windows Installer, then go to small window that probably reads "Disabled".
Switch that to "Automatic", "Apply", then "Start".

This should hep with some of the cases.
