Unable to complete Update 0X80040154: Class not registered

[Guest]

Cannot update, I am behind a firewall, no proxy settings to be able to change..

Can you reach Windows Update? Does it offer repair options when you do?

This set of steps may be relevant:
----------------------------------------------------------------------------
In relation to Windows Update, this error message suggests the following:
--------
Verify that the following files are present and registered properly. Also
make sure that these files are not marked as read-only or system.
? %windir%\system32\wuapi.dll
? %windir%\system32\wuaueng.dll
? %windir%\system32\wuaueng1.dll
? %windir%\system32\wuauserv.dll
? %windir%\system32\wucltui.dll
? %windir%\system32\wups.dll
? %windir%\system32\wuweb.dll
? %windir%\system32\iuengine.dll
--------

So--drop to a cmd prompt and type:

regsvr32 %windir%\system32\wuapi.dll

for example, for the first one on that list.

You can make this go faster by cding to the \windows\system32 (or
winnt\system32) directory, then you don't need to type all the path stuff.

Two of those--the last one, and wuauserv.dll gave me error messages stating
that they cannot be registered, I think that is normal.

Hi Bill,

Just as a suggestion you might want to check out the following freeware tool
called Dial-A-Fix:

http://wiki.djlizard.net/Dial-a-fix

This tool has options for the type of .DLL reregistration to repair Windows
Update and many other similar issues you are suggesting here in a more
convienient user interface. In addition it also covers the related areas of
the OS which can also affect Windows Update / BITS etc.

The light version of this tool comes in at 260K so this should not be a big
issue to download for most users. The full version which includes numerious
external libraries and installers is a lot bigger at ~13 MBytes.

I am just thinking that for some users all of this .DLL registration stuff
might be over their heads and lead to other issues down the line.

Kind Regards

Simon

Thanks--I haven't checked it out yet myself, but I did run it by some other
MVP's to see whether it was something they knew about.

They had some quibbles with it--sorry--I can't find the messages to give a
list--I think that some of the included parts may require WGA to download,
and there were some area where the process suggested (deleting stuff under
softwaredistribution??) involved dumping more than is needed--it is possible
to preserve both history and some other object under that tree with come
care.

At any rate--you are probably quite right that this is a better way of going
at this issue than my cut and paste.

My corp. has sealed me off of Update. Is it beyond the realm of reason to
just provide a means to manually download the signature update? Remember
K.I.S.S?

Defender is pretty much useless to me now on my corporate machine. The Beta1
was quite functional. Oh well, maybe I cab use it at home.

Thanks,

 

[Bill Sanderson]

It's possible to grab the update at home and carry it around, unless you are
locked out of that route as well.

One method is to observe when an update happens, and then take a look at the
tail end of the WindowsUpdate log file--that will have the URL for the
actual download. You can then grab the file and place it on media you can
take to the machine which cannot update.

However, you need to be aware that you are doing an end-run around security
barriers intentionally placed by company management--and there may be teeth
attached to such rules.

Hi

What a mess !!!

If a IT dept don´t allow these updates WD must be uninstalled.

I really hope that this IT dept also blocks installs, gpedit,
C: and every "do it on your own" within all clients PCs.

Running Betas/solving problems during work hours.....

IMHO

Yeah--I'm definitely of two minds about posting that bit of advice (does
that "two minds" translate well?) It can help some legitimate situations,
but it also can be harmful--I'm quite sure that the false positive in 5805
under Microsoft Antispyware raised awareness in a very negative way of the
product on some corporate netowrks.

Hi

Well..... It must be so within a corporate environment.

Byt maybe somes ITdepts approves it and likes the idea.....

It´s another message today about TrendMicros Officescan..........

But this mess belongs to MS, if they put up "bold real warnings" about
known issues within WDs FRONTPAGE and DOWNLOAD page this was solved
easily.

Thanks, Bill, That worked for me in a corporate environment with MS update
disabled, but what a tedious way to continue to keep Defender current!!
Can MS be persuaded to re-instate manual update?

My "..unable to complete update" error number was 0x8024002e
The URL found in home PC log was:
http://www.download.windowsupdate.c..._9183a26a6507a935597d46189e0706b5c4ba323d.exe

Running this file sorted the corp PC, but will it be a different URL each
time?
Although MS update was disabled, I found I could also use this URL from the
corp PC to download the file, so no need to carry it from home.

Corp PC is XP-SP2, whilst home PC is W2K-SP4, but signature update was OK.

[Bill Sanderson]

I expect the URL to change, so you will need to ascertain the URL and import
it for each new definition.

Microsoft has said that they are continuing to look at possible additional
update mechanisms.
