After you purchase a software licence from us, you receive an email containing your licence serial number and instructions on how to use this serial number to activate your software licence. This is done by entering the licence serial number and your personal details at http://www.nch.com.au/activate on our website. Once you have done this, the registration and activation code ("Name - Location - ID - Key") details will be displayed on your browser window and will also be automatically emailed to you. You then enter this information in the software's Registration window.
