I do not think so. You can buy X-Plane DVD (this purchase does not include a digital download product key) or X-Plane Digital Download (you will receive an email confirmation with your product key and this key will allow you to download, install, and use X-Plane without needing any other products) or X-Plane Steam (support for this version of X-Plane is handled by Aerosoft).
