Can't install KB952069

This is a repeat of my posting from 23/12/2008, as I had no reply on that
occasion. I still have the same problem.

For 3 weeks now, Vista has been trying to install KB952068.
I am running Windows Vista Home Premium Service Pack 1.
Every time I run it, it fails with:
"Code 8024200D Windows encountered an unknown error"

Event Viewer -> Custom Views -> Administrative Events shows:
"Windows Servicing identified that package KB952069(Security Update) is not

Clearly this update is applicable to my system, otherwise Windows wouldn't
have kept trying for the past 3 weeks.

Any ideas, anybody?
