When you purchase the SDK License, you get two activation codes: the SDK activation code and the Single License activation code. The SDK activation code is used for activating USB Network Gate on the end-user machines, while the Single License activation code is used to activate the software on the developer’s machine. The Single License is a FREE BONUS which lets you use the GUI version of USB Network Gate for its better understanding. 


If you want to use the GUI version of USB Network Gate for testing and review purposes, take the following steps: 


1. Launch USB Network Gate and select Help --> "Enter activation code" from the main menu. 


2. In the "Activation" window, type the Single License activation code you have obtained from us and click the "Activate" button. 


Note: Activation is required for the USB Network Gate server module only. You do not need to activate the USB Network Gate client module (which is installed at the remote side).
