Attempting to install WSUS 3.0 SP2 on a Windows Server 2003 Enterprise system. I'm asking the setup to create a new database on one of our existing SQL Server 2005 systems. When the setup gets to the "configuring database" step it stops and throws "There is a problem with this Windows Installer package. A program run as part of the setup did not finish as expected. Contact your support personnel or package vendor." The two logs it suggests I look at are below. I'm not seeing any errors that mean anything to me.

Any direction you can give will be greatly appreciated.
