Installation failure for four Office updates

[Ken W]

I have automatic updates for Office turned on. It successfully downloaded
four updates, but failed trying to install them. I've tried again many times
over several weeks. I'm prompted to install them whenever I shutdown. I know
there's a conflict, but I have a lot of processes running and it's like
searching for a needle in a haystack. Is there an easy way to get these
installed and search for the conflict later?

Same answer as posted to Teresa above:

Your Office Source Engine service is probably disabled... Try the first step
from this article and then try the update again:

I read your link, but I don't get any error messages. After I tried to run
the update, it says "The following updates were not installed:"

Security Update for Office XP (KB920821)
Update for Outlook 2003 Junk Email Filter (KB920907)
Security Update for Office XP (KB921567)
Security Update for Office 2003 (KB921566)

What does this mean? What should I do?
Thanks a lot,
