If you are an active customer of the Ez3D Plus application, then you are entitled to customer support. This application is not publicly available because it's expensive and it's used in the medical field. It's known for developers of these apps to avoid making it public (downloads, user guides, troubleshooting, etc), therefore, if you have issues with it or want to know more about it, the only way is by contacting them.
