**How does product activation work?**

Product activation is a software-based license management technology. The process verifies that your serial number is valid and that the software has been activated only on eligible servers. An activation request includes:

* The product information (such as domain name, serial number, and product code)

**I have a serial number but it doesn't work.**

Please verify that you entered your serial number and product key exactly as displayed in the email.

If so, then submit a request via our [Problem Form](https://m.me/314999428558770). Be sure to include the product name, your current serial number, and any error messages that you are receiving in your support ticket.
