C/C++ programming with OrnataV2

Hi

I just got an Ornata V2 keyboard and I would like to program in C/C++ with it.

But I don't know what I need to download and to setup to.
I downloaded the "C++ Sample App" (https://developer.razer.com/works-with-chroma/download/) but it does not seem to work...
Maybe the keyboard isn't compatible ?

Please help me !
