Unexpectedly Failed Installation Of SQL Server Express Edition

Pls help me on this issue...

The min reqt olny says Windows XP Service Pack 2. So, whether it is Pro or Home I assume this Edition will run. MY system is XP Home SP2 with 2GB RAM and Dual Core Intel Processor. Is this the problem? There is no error displayed on the summary.txt and I do not know how to read the log file. Pls help... Or do I need to upgrade to XP Pro?

This is the log file details:
