Successful CUDA Installations?

So, I’m trying to track down a problem with my CUDA project not linking properly in Windows 7 x64, and trying to find out if anyone has successfully compiled projects in Win7 x64, with what CUDA toolkit, and possibly what their secrets are! :rolleyes:

So far my status is:

Win XP x86, VS 2008, VC++ 2008 & 2010, CUDA 3.0 = SUCCESS
Win 7 x64, VS 2008 & 2010, VC++ 2008 & 2010, CUDA 3.1 = FAILURE

Anyone had better luck with 64-bit OS?

Thanks!
