License management: 

Commercial licenses are managed by at least one unlock key, coupled with online verification of the license/key (since 2017). The customer receives by email the unlock key which once entered will remove all the trial limitations and activate all the benefits of the commercial license.

Unlock keys start with VSO_V4K_ , they are very long thus they should not be entered manually.  The copy/paste feature of the operating system need to be used to enter the key. With the online activation system, "Key is for another software" is something of the past. Any unlock key attached to a customer license(s) can unlock any of his licensed software. A customer can also use his/her registration email address for all software as a simpler alternative to the long unlock key. As a result, customer will receive a verification email with either an activation link to click, or a pin code to enter in the software to unlock.
