windows update fails on windows vista x64 because of KB980182

I believe a corrupt install of KB980182 for windows vista x64 is causing windows update to fail. As a result I cannot run windows update, or install/uninstall updates via the control panel. I have run the readiness tool which includes checksur, and I've received the following output.

Does anyone know how I might be able to rectify this situation without a repair install/in place upgrade?

I understand it might be possible to extract KB980182 and copy the files to the packages folder and this might fix the situation but I haven't worked out how to do this yet.

This is a security update for Internet Explorer. My suggestion would be to remove IE completely (so that it reverts back to IE7) and then reinstall IE8 from a standalone installer.

Easiest way to kill IE8 is to visit http://support.microsoft.com/kb/957700 for details.
