I cannot get the activation key to be accepted even though it is current and emailed to me by Stardock. I am trying to set up fences on a new laptop.

Searched my backups (external drive) for the original download in 2016, (v2) from my now defunct desktop.
Copied this over to the new laptop and applied key sent by Stardock.
Bingo! It works
