Have you tried inserting your Office CD into the appropriate drive bay
before attempting to install the update(s) again?

To reinstall Windows Update Agent - download the relevant file from one of
the links provided above and save it to a drive where Vista is not loaded
because the file cannot be launched directly from the system root directory.

Click Start, click Run, type: "D:\WindowsUpdateAgent30-x86.exe /wuforce"
(without quotations) and then press Enter to install the Windows Update
engine.

Note: There is a space between "D:\WindowsUpdateAgent30-x86.exe" and
"/wuforce"

D: is the drive where Windows is not installed (ie a flash drive or a 2nd
hard drive etc)
