Installing SQL Server 2005 on Windows XP Pro x64

On MSDN, I have downloaded "SQL Server 2005 CTP - September 2005 - Enterprise Edition - 64-bit Extended - Servers (English)" that I am trying to install on WinXP Pro x64 (EMT64 machine).
Unfortunately, I am not able to install SQLSRV2005, indeed during the setup the option such as "SQL Server Database Services" are grayed (i.e. not clickable, idem for Analysis Services). The only thing that I can select is "Workstation components".
Is it possible to use SQL Server 2005 on a WinXP x64 OS ?
Thanks in advance,
Joannes
Enterprise Edition isn't supported on WinXP. Please see the following link for system requirements:

Installing SQL Server 2005 Developer Edition 64-bit extended on Windows 2003 SP2 cluster

Hello

I've installed Windows 2003 SP2 in a stand-alone cluster (will be adding a second node later). I'm now installing SQL Server 2005 Developer Edition 64-bit extended and would like to have the "Create a SQL Server Failover Cluster" box to not be grayed out. Even when I check the "SQL Server Database Services" box, it still has the cluster box grayed out.

Any idea's?

TIA!

Have you created and configured the cluster service (MSCS)?|||This is resolved. As per usual, SQL 2005 seems to install with more success when you copy the cabs local to the machine, and then run setup (versus over the network).thank anyways Arnie.
