Get the product and the license key

This means that the license information is delivered electronically (by e-mail or via HelpDesk) and no physical product is shipped. License information includes a "License Ticket" and instructions for how to use this license ticket to get access to license keys and downloads.

You can request a digitally signed PDF or a signed paper copy of the license agreement.

You get access to the license keys, special downloads for registered users and source code (where applicable) via My Control Center. You will need to create an account on our site (this is done via My Control Center as well) to get access to downloads and license keys.

All orders are processed by hand within 24 hours after the payment or a purchase order has been received by Avangate (if you ordered online) or by us (if you paid with a wire transfer or check or sent a purchase order).

If you have not received the registration e-mail or other message from us within 24 hours (usually this happens because of antispam filters which block e-mail registration letters), please use our Web-based Helpdesk system to request the license.
