I just installed Nevron Vision for SharePoint 2007 on our Testign server (beofore go produciton server ), then edit page---add "Nevron Chart for SharePoint 2012 vol.1" --Run chart Desinger,

 I don't see the licensing tab (see attachment screenshot ).

also, I will install this on production server later, do I have to install this first, then send the web server ID to sales to get the licnese ?  can I get the license key before the installation ?

Hello Dana,
In order to see the licensing tab, you will first need to connect to some data from the Data Source tab.

Regarding the production environment – yes, you need to first perform the installation and then send the machine ID. Currently there is no option to receive the license before the installation – the license is bound to a machine ID.
