Security check shows need patches for MS04-027 & MS04-028

[bulldog]

Microsoft Office update says I need 'Office XP Service pack 3 (English
version)' yet when I click on 'about Microsoft word' it says 'Microsoft Word
2002 (10.2627.6626) SP3.

REQUIRED UPDATES

Office XP Service Pack 3 (English version)

Does this mean I allready have Office XP Service Pack 3 ?
If so why does Security check say I need patches for MS04-027 & MS04-028?
Why does Office Update insist I update Office XP Service Pack 3 and won't
let me select other required updates until Office XP Service Pack 3 is
updated?
( I am using Windows XP )

I tried downloading using the office update instalation wizard and with
my Office XP CD in the CD drive but message was 'Instalation
unsuccessful'.
I tried again with Office CD out of drive and got the message Use
source Microsoft Office XP Professional with FrontPage. I reinserted CD and
clicked on OK and again got message 'Instalation unsuccessful'
I tried this with both CD's.
I then tried downloading the fullfile version and got the message
'Error 1328 Error applying patch to file C:|config.msi|PT237.tmp. It has
probally been updated by other means, and can no longer be modified by this
patch.'
Can you help - Tell me how to download these patches / updates?
