Does not work at all you double click the .exe and you get nothing. However a patch is coming out to make it 64bit compliant in the near future.

Patch 1.31. Works perfect. Even smoother than under XP32...note: I did not install it fresh, I simply used the installed game directory from another partion and created a shortcut to my XP64 desktop.

Download 64 bit patch from AMD ..

Runs smoothly and looks great with the 64-bit patch, but i've had the odd freeze on my machine, which is a bit frustrating when there are no quicksaves! Other than that, you have to see the differences to believe it in 64-bit! 8/10. :)

Have since upgraded my Radeon 9600xt to a GeForce 6800 GT and game now runs beautifully fully patched with 64-bit binaries on x64. The extra content is a little superflous, but the added 64-bit textures are a sight to behold. Enjoy this one, and kudos to Ubisoft.

Far cry version 1.4 plays fantastically.

The only issue is that the mouse will not work unless you set the controls to default...then assign the keys. Apparantly, this issue has been around for a very long time and i just never noticed before (not a vista issue) :)
