Licenses are applied and activated per user and per PC that Tic Tie Calculate is installed for. For example, if a single user uses Tic Tie Calculate on two PCs this will be two licenses used.
There is not a management system available to see which users have activated a license. This is something that would have to manually tracked by the business.
Support is only able to see the total amount of license purchased and how many of those are available for use. If you need to have one released, for example for someone who has a new PC, a request would need to be sent to Support and we can release that license for a new activation.
