A method and arrangement for limiting the number of simultaneous users of a software ( 106 ) protected by a licence agreement. A start request is sent from the software to a lock unit ( 108 ) when the software is activated by a workstation ( 102 ), after which it is investigated whether any physical licence unit ( 110 ), connected to the lock unit and corresponding to the software, has a free user position. The software is started if there is a free user position, but is terminated if there is free user position. The solution provides for increased control and security that the number of simultaneous users cannot exceed what is covered by the licence agreement, as well as a simple upgrading of licence agreements. |
