Oracle 10g 10.2.0.1.0 needs to be upgraded to 10.2.0.3.0. Where do you get it?

I am trying to upgrade to VitualCenter 2.5

I am using Oracle 10g at version 10.2.0.1.0. Ineed to get to 10.2.0.3.0 per the install guide.I have hunted all over the Oracle site. The only version that is 10.2.0.3.0 is for Vista. Any idea where I would get it for 32 bit windows server 2003?

Thanks,

Brian
