In fact most of Eltima products are shareware. It means that you can download the free trial for evaluation and if you like the product order the license. I.e. you can try before you buy. So, in our case purchasing a full version is actually the same as purchasing a registration key.
Upon placing the order and paying for it you receive a registration info which is to be entered into the demo product in order to get fully functional version.
Please, check the email you have received from our billing operator with your Registration info, it usually contains download links to the product you ordered. Alternatively, you can find the download link to the product you purchased at https://www.eltima.com or https://mac.eltima.com/
