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

I'm trying to run the Windows Updates on a workstation running XP Pro SP1, but I keep getting the following message:

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

Click option 1: Register or reinstall the files for me now (Recommended)
Click option 2: Let me read about more steps that might be required to solve the problem."

Clicking option 1 makes out like it's doing something useful, then goes back to the Windows Update screen offering Express or Custom.  However, that screen is only on for a split second, then it goes right back to :
"Files required to use Windows Update are no longer registered or installed on your computer. To continue:"

Clicking option 2 sends me to a place where I can "search for yourself".  Not any help at all.

Try re-registering the following files:
Start > Run > regsvr32 wuapi.dll > OK
Start > Run > regsvr32 wups.dll > OK
Start > Run > regsvr32 wuaueng.dll > OK
Start > Run > regsvr32 wucltui.dll > OK
Start > Run > regsvr32 atl.dll > OK
Start > Run > regsvr32 MSXML3.dll > OK
Restart the computer, and then try Windows Update site again
Greetings, martit01!

Let's try stopping the services, re-registering the files used and restarting the services used for Windows Update and see if that makes a difference.

Create a new text file using Notepad or your favorite text editor and copy and paste the following lines into it:


      %windir%\system32\net.exe stop bits
      %windir%\system32\net.exe stop wuauserv
      %windir%\system32\regsvr32.exe %windir%\system32\atl.dll
      %windir%\system32\regsvr32.exe %windir%\system32\jscript.dll
      %windir%\system32\regsvr32.exe %windir%\system32\msxml3.dll
      %windir%\system32\regsvr32.exe %windir%\system32\softpub.dll
      %windir%\system32\regsvr32.exe %windir%\system32\wuapi.dll
      %windir%\system32\regsvr32.exe %windir%\system32\wuaueng.dll
      %windir%\system32\regsvr32.exe %windir%\system32\wuaueng1.dll
      %windir%\system32\regsvr32.exe %windir%\system32\wucltui.dll
      %windir%\system32\regsvr32.exe %windir%\system32\wups.dll
      %windir%\system32\regsvr32.exe %windir%\system32\wuweb.dll
      %windir%\system32\net.exe start bits
      %windir%\system32\net.exe start wuauserv

Save the file with a name of "WUREPAIR.CMD" someplace you will remember such as your Desktop or a directory like C:\TEMP including the quotation marks in the filename so the text editor doesn't accidentally save it with a .TXT file extension.

Run the WUREPAIR.CMD file from the Command Prompt (filename: CMD.EXE ) or by double-clicking on it.

martit01,

If the above does not work, go to Start > Run and type

regsvr32 wuauserv.dll

war1,

"http://help.lockergnome.com/lofiversion/index.php/t37477.html"

I found this website before I posted my problem here on Experts-Exchange, but didn't try it because that OS was Windows 2000 and I'm using XP Pro. Should I still follow your suggestion, even though the operating systems are different?

Quick typing war1, which DLL do you think it is ;-)
DeltaFire,  it didn't work.



war1,

WUREPAIR.CMD didn't work. :-(

When I ran "regsvr32 wuauserv.dll" I got the following error:
"wuauserv.dll was loaded, but the DllRegisterServer entry point was not found.
This file can not be registered."

martit01, did you create the WUREPAIR.CMD file that I posted above?
war1,

Yes, I created the WUREPAIR.CMD file and ran it, than rebooted.  I even ran it twice, but still didn't fix the problem with windows update.
HELP, I'm about ready to use my second and last Microsoft call on this one???
Why dont you try reinstalling SP1 or upgrade to SP2 right away.
Or you could try to manually reinstalling Windows Update controls:

Try the following commands:
net stop wuauserv
regsvr32.exe wuapi.dll
regsvr32.exe wups.dll
regsvr32.exe wuaueng.dll
regsvr32.exe wucltui.dll
regsvr32.exe MSXML3.dll
regsvr32.exe qmgr.dll
regsvr32.exe qmgrprxy.dll
net start wuauserv
I did fresh install and it's now fixed.  Maybe not the quickest solution, but the updates are running.

Thanks to everyone who helped.
martit01, glad Winddows Update is fixed.
