Can't integrate Visual Studio with CUDA

I installed Visual Studio 2012 & CUDA Toolkit 7.5(cuda_7.5.18_win10) on windows 10. But while installing cuda I am getting error as “No supported version of Visual Studio was found.” even though I have already installed Visual Studio.
Is there any other method to integrate CUDA with Visual Studio or to write and run CUDA programs without using Visual Studio in Windows?

Which version of VS 2012 do you have? Is it VS2012 express?

Is your windows 10 a 64-bit win10 install?
