Hey, I'm not a dev of this project, I just submitted a pull request, but I'll reply anyways.

1. Are you sure you have downloaded the models and placed them in the correct folders?
2. Are you sure the Visual Studio tools are correctly installed?
3. Are you sure your Python version is the appropriate one and you have installed it correctly? (see below)
