Excel 2003 update failure

[Jamie]

Hello,
I am attempting to install the current Security Update for Excel 2003
(KB9055756) and with each attempt I receive the follwoing message:
"Updates were unable to be successfully installed"
"The following updates were not installed
Security Update for Excel 2003 (KB9055756

I also receive a similar message for the 2 current Outlook 2003 updates.

I would appreciate any advice on what may be causing my problem. I have
Office 2003 on a desktop and laptop with the same results on each. I have not
had any problems with Office updates prior to these most recent 3 Security
updates (1 for Excel and 2 for Outlook)

Thanks!
