Network Licensing and Terminal Services

Terminal Services are not supported by our regular, "single instance licensed library". Running library over the network requires network license, which is not bound to any particular workstation on the network, but rather to the network itself. 2DTG offers network licenses both for RTL and Dongles providing the ability to host multiple, simultaneous client sessions. Activating / deploying the DLL on one instance (either workstation or server - “seat”) will enable all seats (up to the total number of purchased network licenses) to have access.

RTL Network Library/License - QR Code SDK, NetFloat – contact Customer Center.

For Network license on Dongle,

  • select network option you need at the time of order, or
  • purchase network upgrade (if you have already acquired dongle license from us before).
