If you purchased a license to one of our products, but have lost or never received the registration information (user name and serial number), you can recover your registration information.
If you have trouble entering the serial number correctly into the software: cannot find where to enter it, confused with all the letters and digits, etc., we have detailed instructions for software registration for all our software.
If you have never purchased a license for one of our products, and therefore you do not have a serial number, you need to visit the relevant product's web page (see links in the footer below) and click on "buy new license" to purchase a license and receive a user name and serial number, immediately via email.
Please do not share your serial number with anyone as doing so may likely result in the number being deactivated.
