When an activated license is presented to the license service, an equivalent machine-locked license is returned which can only be used on the machine from which the activation took place. The license-ID and the machine code of the machine are recorded in the 'Activation' table of the license service database.

Sometimes it may be necessary to de-activate the license from a particular machine, so that the license can be activated again from a different machine without hitting the maximum activations limit specified by the license. For example, the user may wish to migrate your software from one machine to another. In this case, you can use the CCryptoLicense.Deactivate function in your software. This method communicates with the license service and removes the activation record for the license-machine code pair from the 'Activation' table of the license service database. This frees up a slot for another machine to be activated using the same license.
