It seems there are a lot of people who are having problems with updates 
downloading but not installing.  I now have this problem on two different 
computers in my house on one, the list is quite long now:

Update for Microsoft Office Outlook 2003 Junk Email Filter (KB974771)
Security Update for Microsoft Office 2003 (KB972580)
Update for Microsoft Office 2003 (KB978551)
Security Update for Microsoft Office Word 2003 (KB973443)
Security Update for Microsoft Office Excel 2003 (KB973475)
Security Update for Microsoft Office 2003 (KB974554)
Security Update for Microsoft Office 2003 (KB975051)
Update for Microsoft Office Outlook 2003 Junk Email Filter (KB976882)
Security Update for Microsoft Office Outlook 2003 (KB973705)

all failed to update.  

I tried scanning manually and the new updates that were required downloaded 
and installed fine.  I think it is either a problem with the Automatic 
Updates program or is a virus or perhaps is a compatibility issue with 
McAffee?  Anyone else out there having this problem runing McAffee suite of 
products?

Thanks

Does anyone know what is Code 646 is what to do to around this code and 
complete the installation ? I have McAfee protection.
Thanks.

IOW: No Office Update at all installs on your machine, true?
Make sure, the "Office Source Engine" is not deactivated in the Service
configuration (Start -> Run/Searchbox -> services.msc [Enter/OK]).
See http://support.microsoft.com/kb/903774/en-us for your reference.

What exactly is meant by "scanning manually"? Which Windows version are
you using?

Bye,
Freudi

or Windows 7. I had the same problem when I had to get the new Webroot 
Spyware engine and I seem to be having the same or similar problem. I cannot 
download Internet Explorer 8 or IE7 or the new windows7. I had same problem 
when I had to download the new Webroot spyware engine and McAfee. I turn off 
everything on all the programs I can think of, disable any security on 
Internet explorer and still cant. Last time I was told to download Google 
Chrome and I did and got the new engine but now cant get anything to download 
again, even from Google Chrome. I have cleared my history and cookies and IE 
pages etc. No luck. Would like an answer if you ever get one.

Try downloading and installing the updates separately in order to get more 
information about the error that is causing the failure. In my case the 
installation failed because it was looking for an invalid drive. Re-instating 
the drive cured the fault. Same could probably achieved by modifying the 
relevant registry key.
