Create a .C2V file for a license update

Since a license update can be applied to only one specific dongle, for an update of your licenses, we need a .C2V file which is created with your dongle. To do so, please visit http://localhost:1947 and select Sentinel Keys from the menu on the left. In case of multiple present dongles, select the dongle you want to update and click on the button C2V in the according entry. Download and send us the C2V file to To update your dongle, we will send you a .V2C file with the updated license information (see also How to activate/update your licence above).
