Error 89B in update


I am trying to install the three updates; KB973475, KB973443 and KB975958.
When I do I get a failure with error code 89B. Have been through the help
screens with no success. Anyone else out there have a solution to this
problem. I am running Windows 7 Home Premium (64 bit), Microsoft Office 2003
on a dual core AMD 6000 system with 4Gb memory and about 150Gb spare on the
hard drive.
