Question:
How can I disable the access to the Viewer in the machine executing the E3Server?
Solution:
To do so, set up the Viewer Groups in the application domain options (right-click on E3Admin‘s icon on the System Tray, then choose Domain–Options–Viewer Groups). On this tab, you will be able to uncheck the access to the Viewers (Full and Only).

You can use the Viewer license to open a Viewer in another machine on the network, since you will not use it in the computer executing the E3 Server.
