Installation Problem SQL Express 2005 on Win 2003 SP1

Hi, I've a problem to install SQL Server Express 2005 on Win 2003 SP1.
Do you know how to solve the problem ?

It displays error message after I click the setup file:

SQL Server Setup unexpetedly failed. For more information, review the Setup summary log file in %ProgramFiles%\Microsoft SQL Server\90\Setup Bootstrap\LOG\Summary.txt

Then I open the Summary.txt, it contains:

Microsoft SQL Server 2005 9.00.1399.06
==============================
OS Version : Microsoft Windows Server 2003 family, Standard Edition Service Pack 1 (Build 3790)
Time : Thu Sep 21 11:17:18 2006

And review the SQLSetup0001_PCNAME_Core.txt in the Log Files directory:
