If you manually copied the application instead of installing it, the program will ask you to activate it every time it runs.You should re-run the installer.

It’s also possible that antivirus software is preventing the license file from being saved, or that the user cannot write to the license file location. You could try disabling the antivirus software temporarily, and running the software as an Administrator (just for the activation).

For reference, here are the license file locations per OS and Dragonframe version:
