Security Update KB954430 Reinstalls Repeatedly

This problem is now resolved: here is the fix that worked for me in case anyone else can use it. I tried a fix I found by Googling, applied it, and it did not work. This morning I called the Microsoft toll free number for Security issues (on their web site reached.Go into add remove programs and uninstall the msxml update kb945530. Close and go to windows update (start, all programs, near top of list). Click on express update: the update should now show on the list. Reinstall the update, then restart your computer.This worked for me and I hope it helps someone else who has the problem.
