If the machine on which you are installing the Easysoft product has a connection to the internet, use the online licensing method, which requires minimal intervention from you.
If the machine on which you are installing the Easysoft product doesn't have a connection to the internet, use the offline licensing method. This involves the additional steps of giving your machine number to us, and applying the license keys when you receive them.
Offline licensing can be done using e-mail or the Trial License Request or Full License Request pages at the Easysoft web site. If you use the Easysoft web site, log in using the details of the registered user who downloaded the software.
