GuideSIGN Markings is normally protected from illegal use by means of an authorization. For GuideSIGN Markings, this will be the same authorization used by GuideSIGN Pro and part of its licence. When running GuideSIGN Markings standalone systems for the first time, an authorization code is required. This code can be obtained from the Keysoft website or by contacting support directly. On network license systems, the licence authorization is obtained from a pool of licences on a server each time GuideSIGN Markings is used.
