New Post: "Run CUDA test" produces compilation error in Cudafy Viewer and error: "nvcc fatal : Cannot find compiler 'cl.exe' in PATH"

Downloaded and ran the giant 1GB Nvidia CUDA installation. Then I ran Cudafy Viewer and clicked "Run CUDA Test". Here's the output. As you can see, the Compilation error "." is quite cryptic. What can I do to fix this?

Platform=x64
Checking for CUDA SDK at C:\Program Files\NVIDIA GPU Computing Toolkit\CUDA\v7.5\bin\nvcc
CUDA SDK Version=7.5
Attempting to cudafy a kernel function.
Successfully translated to CUDA C.
Attempting to compile CUDA C code.
Compilation error: .

I also get this problem when I try to run the "CudafyExamples" project:

ArrayBasicIndexing
Cudafy.CudafyCompileException: Compilation error:
nvcc fatal   : Cannot find compiler 'cl.exe' in PATH


Please add the Visual Studio VC bin directory to PATH in Environment Variables..

What's the quickest way to fix the above problems?
