Hi Kostya, I did purchase the unlocker separately long time ago before Mobisystems. I didn't know it has changed since then and not sure how to do it I guess. I always download both program & unlocker when change to new phone.
Secure folder is the new name of Knox. For S8/ S8+ and Note 8 are using Secure Folder now where you can have apps in two different environment just like having two phones, one for work the other for personal. eg. two whatsapp, facebook, aquamail, etc.
