Update installations fail

[hereforhelp]

About two weeks ago three updates appeared but failed to install:
Security Update for Microsoft Office Excel Viewer 2003 (KB951589)
Security Update for Microsoft Office 2003 (KB953404)
Security Update for Office 2003 (KB954478)

They keep insisting they want to, but failing. Getting to be irritating. Anyone know what's going on?
Using WIndows 2000.
