The problem is now resolved, thankfully!
I did what you suggested but the updates
would not install individually at all, so
i clicked on the MS get help link on the 5th
update & found there is a hot fix available.
So i downloaded the hotfix which installed
the update automatically & then installed the
other 4 updates & success, windows is up to date.
Below are the 5 updates concerned as listed & worded:
security update for MS office visio viewer 2007 (KB973709)
security update for the 2007 MS office system (KB972581)
update for MS office info path 2007 (KB976416)
security update for MS works 8 (KB977304)
update for MS office word 2007 (KB974561)
Ive added these as they might be helpful to someone with
the same error codes looking for a soloution.
Thanks to Broni for the time taken out to help & it was your
suggestion to install individually that led to the soloution.
