Hi @DDfitforlife. Thanks for being part of GoDaddy Community! You would have to setup some kind of registration system on your site prior to giving visitors access to the downloadable file. You could probably do this by setting up something like Woo Commerce, though there may be a less involved way of doing it. Other members of the community might have additional suggestions. I moved your post to our WordPress board to hopefully get more attention to your question.
