Usage Scenario for Offline Activation / Deactivation

Hi.

 

Consider the following scenario:

 

1) User goes to Self-Help Portal and gets Computer Key for his Activation Key.

2) User activates Computer Key in the desktop app.

3) User goes to Self-Help Portal and deactivates this Computer Key and issues a different Computer Key for another machine.

4) User activates this new Computer Key on another machine.

5) Repeat steps 3+4.

 

Result: user gets unlimited number of activations per single Activation Key.

 

Is there a way to prevent this apart from removing the option to deactivate a license in Self-Help Portal? We need to allow users to transfer their licenses to different machines.

 

Thanks.

 

Best regards,

Tony.

  If the computers are offline, there's not much that can be done besides removing the ability to deactivate a license in the QLM Self Help page.

  If the computers are online, the LicenseValidator class already handles this scenario by calling an API called IsIllegalComputer. If it detects a computer as illegal (meaning that the license is valid locally but on the server the same license is activated for another computer), it will automatically delete the keys on the system.

  Would setting the maximum number of offline days help with this problem? You cannot stop someone from blocking or turning off the internet connection. You could limit this problem though by setting the number of days that can pass before requiring a "check in".

  Setting to something like 20 or 30 days should be more than enough to catch a user out. If they do require more than that number of days they could do a manual check in with their phone through manual activation? This should discourage anyone who wants to play around and try to cheat by giving the code to friends. It would make it too much effort and too complicated to be worth doing. You could even set it to something small like 5 days offline. It would be easy to do a check in after 5 days and would not cause users an annoyance. It would stop people from cheating though, would not be worth it....

  That's a good suggestion. Thank you for the input.
