Set up a multi-user license

The following describes how to make a multi-user license available on your network. Im Folgenden wird beschrieben, wie Sie eine Mehrplatzlizenz in Ihrem Netzwerk verfügbar machen.

The procedure at a glance

A multi-user license enables concurrent use of infra CONVERT on a specific number of workstations (clients) simultaneously (Concurrent User Licensing Model). The clients obtain their temporary license over the network from the ELIAS License Service, which manages the multi-user, single-user licenses. The PC (ideally a server) on which the license service is installed should therefore be constantly accessible.


Install the ELIAS License Service on the server. The installation file can be downloaded from the download area on our main pages.


Install infra CONVERT on any client PC and enter the path to the license server in the software. The installation file can be downloaded from the download area on our main pages.

Note There are no differences between different functionalities during the installation. Even if an installation is used as a demo version, all functions can be unlocked for them with the appropriate license.


You send the individual registration key generated for this installation together with your contact data by e-mail (A) to your CAQ/MES system provider respectively the service of ELIAS GmbH.


The license file, which you also receive by e-mail, is loaded on the client PC in infra CONVERT. The license is now automatically forwarded to the license server.


In every subsequent installation of infra CONVERT, only the path to the license server needs to be specified.
