The Manage Product Download module control allows customers to download virtual products they purchased (e.g. software, e-book, music, etc.). This module should reside on a SSL secured page visible to registered users only (e.g. typically under some “My Account” page).
As a security measure, the download link for a product will only appear once the order has been marked as “Paid” or "Completed".
Please see Downloadable Products for more information.
