Running SQL Server 2005 Dev Ed. and Express Ed. side by side.

I recieved the same error running both the SQL Svr Express SP1 and the SQL Svr SP1 updates. I resolved the problem with SQL Svr Express by installing the SQL Svr Express with Advanced Serives pakage. The SQL Svr SP1 still errors out with this message: Unexpected error ocurred: The following unexpected error ocurred <blank message> with an ok button. The following is the contents of the installtion log file:

Moving to Setup so they can troubleshoot the issue w/ SQL SP1 patch.
