I don't use Windows for development but that error message makes me 
think cl.exe is not found to be executed.

dmd relies on system compiler programs for its ImportC feature. cl.exe 
seems to be the compiler. I think it is the compiler.

Can you run that program from the command line?

Internet makes me think Visual Studio does not install it by default.

Standard D programs don't need a C compiler; dmd is the D compiler. It 
needs a C compiler (to preprocess C sources) for ImportC.
