Hi ,I just checked the list of installed updates on my machine and that one is installed .successful on the 25/02/2009

Here It Is.

Hey i found out the problem this morning. Turn off UAC Control. In control pannel goto user accounts & turn it off then install your update ! Have Fun

UAC is already turned off

UAC if off already for me too....
Think I will play with the settings (on/off) and see if it makes a difference though.

I had the same problem and already solved.
If you activate your windows seven using replacing method, you have to rollback to original non-activated state, then install updates and using the official product ID to activate.
