64-bit Windows & Blender?

I just started upgrading to Windows Pro 64 bit.
But now I noticed there is no 64 bit blender for windows is the 32 bit
version go to run, or am i screwed?

Sorry never mind by bro installed on his comp and
i worked, so thanks any way.

there are some technical reason why there is no 64bit build - my guess is that some of the dependences need a lot of work in order to be 64bit complaint under windows.
