Unity3d not working properly on a WinXP 64 platform?

Hi All,
I downloaded the latest version of Unity 3d and am not seeing terrains or 3d objects when I attempt to put any of those items into my scene. Any idea if Win ≈π is supported? I got an error message in Unity asking me to install a patch but that is only for win 7 or vista…very frustrating…

I solved this by upgrading to windows 7.
