I find that I am able to open raw files from the Nikon D3s with Camera Raw 6.4.1 on a 64-bit version of Windows 7 while Photoshop is running in 64-bit. Are you able to open other raw files, such as DNG (there is a sample one in the "Sample" folder of Photoshop)? My best guess at this point is that you are missing the 64-bit version of the camera raw plug-in. Try running through the steps in this document:
