Windows XP X64 Installation Issues

I'm trying to install SolidWorks 2009 x64 edition on Windows XP x64.  The install appears to go smoothly, but when I launch SolidWorks, it never opens.  I have verified that my system meets the minimum requirements for 2009 and have verified that I am running the correct version of the video drivers for my card.  The machine is a Dell Precision T3400.  Has anyone seen a similar issue?

thanks,

Justin
