error: nvcc cannot find a supported cl version

Hallo,

I have used for my Optix-Project MS VS Express 2005. All works good.
Now i try to use MS VS Express 2013 and just get “error: nvcc cannot find a supported cl version”
But i see the file cl.exe in C:\Program (x86)\Microsoft Visual Studio 12.0\VC\bin

Can anyone give me advice?

Check that C:\Program (x86)\Microsoft Visual Studio 12.0\VC\bin is in your PATH environment variable.
