DirectX interop in 3.0 (Nvidia card)

I am trying to run the **d3d11_interop** example, but it crashes on `initializeContextFromD3D11Device`. When trying to debug this function, I can see that `clGetPlatformIDs` returns two IDs (as expected, I have an integrated Intel GPU and Nvidia GPU card). A call to `clGetDeviceIDsFromD3D11KHR` throws an access violation exception for Nvidia card (Regardless whether the GPU being currently used in Intel or Nvidia). For the Intel embedded GPU the interop seems to work. Am I missing something with Nvidia drivers? I have installed the latest Nvidia driver. Same happens in 64bit (CUDA 7.0) and on 32bit (CUDA 6.5).
