Manually Deactivate EXE file

If I wanted to offer 3 payment plans for my product that is downloaded by users. How can I deactivate the product (program) from being no longer accessed?

Program would not be done by online activation. I would manually activate the program using xls.

In XLS Padlock 2022, customers can now enter a new activation key from the Welcome screen. This will replace the existing one (if any).

How is that, i need video for that

When customers entered their key and activated the EXE. On next runs, the Welcome screen will show a button to let them change the activation key if needed.

Please can you show me screenshot, because i didn’t see that or send me video link if available

Which version has this option ???

Latest version.
