There is often confusion on how Stand Alone is licenced in order to work properly. The main point in the confusion revolves around the fact that a 10 user licence with 3 additional stand alone workstations is not licenced as a 10 User system and can as a result be configured in such a way as to allow customers to get a Status 161 error. In order to correctly licence a 10 User System with 3 additional Stand Alone Workstations we (Technicians) must licence them for 13 users, and 3 Stand Alone Workstations.
