[CUDA 5 in Visual Studio 2010] Unsupported host compiler 'x86_amd64? error

Hi fellow CUDA programmers,
I have installed CUDA 5.0 on my PC, Windows 8 x64, and tried to import a project form another one with only CUDA 4.2 installed. While cleaning the project I get the following error:

nvcc fatal : Unsupported host compiler 'x86_amd64′

I see that the problem is the other PC had diffrent archtecture or somthing, then the one that I’m trying import the project on. But the question is what, where and how can I change project settings/options to make it work? In CUDA C/C++ options, project properties window, in command line tab is a compiler option (among others):

… --cl-version 2008 -ccbin “bin\x86_amd64” … // the ‘ccbin’ part

The problem is that I don’t know how to change it. Is it this part causing the problem? Where can it be changed.

Bless You,

Got it solved - reinstalling NSight for Visual Studio fixed the matter.
