Express SP2 Install Failure

Hi,

I'm running SP2 to upgrade my current instance of SP1. At the point of "SQL Server Database Services | Configuring components..." it stops with the following error:

#####
Microsoft SQL Server 2005 Setup
------------------------------
The installer has encountered an unexpected error. The error code is 2259. Database: Table(s) Update failed
#####

The setup log contains the following detail in the "LaunchFunction"

I have installed the same SP2 on another machine (Both XP SP2) without further problems. The only difference between the two machines is the one with errors has another instance of SQL 2005 (Not express) as the default instance and the Express named instance I am upgraded. The second machine only has Express named instance.

Any help appreciated.
