If you start Netcam Studio X there should be an icon looks like a key in the upper row. If you run a licensed version like the one in the picture above you do not have that key and cannot add a license. If you go to C:\ProgramData\Moonware\Netcam Studio\Server there is a file called Lic.dat. Remove that file nad start Netcam Studio X. There you should have the key icon. If you still do not have that you need to contact support so they can release the license from the hardware.
