To use IzoT CT on a PC or Virtual Machine (VM) you need to activate an IzoT CT (or OpenLNS CT) and an IzoT Net Server (or OpenLNS Server) license. Each CT Activation Key comes with two sets of licenses so one person can have CT on two PCs.
IzoT Net Server (or OpenLNS Server) needs to be activated before you can use it. Each IzoT Net Server Activation key comes with one license.
Solution: Activate the IzoT Net Server or OpenLNS Server license
