Problem While Installing SQL Server 2005 Express Edition On Windows 2000 PRO SP4...Can't Install!!!

Hi everyone...

I'm facing a problem while installing the SQL Server 2005 Express on Windows 2000 Pro with SP4.

After finishing the downloading from Microsoft I start the installation and things seems to go ok but during Extracting Files step a message appears "SQL Server Setup unexpectedly failed. For more information, review the setup summary log file in %Program Files%Microsoft SQL Server90Setup BootstrapLOGSummary.txt" and it terminates the installation.

I located the log file and open it but can't understand the problem..I copy the text and paste it here for anyone who can understand it.Please, it is very importand for me to work with SQL Server for my project. Any advice or information or anything else???

Thank you all,

HERE IS THE LOG FILE:
