The above did not work. Tried using the Windows installer page and it told me that each of the three programs were not for my computer. Every time I try to do updates I get error code 80070641.

Hi I have stopped the Windows Installer and retried installing the Office 2007 System update (KB2539530) and still get the same error message - 80070641 . I am running Windows Vista Business and Office 2007 Professional. Please advise Chris
