Error: "There are disabled network adapters on your system"! What should I do?

If you are having problems activating accusonus products on Windows, you might need to Enable all Network Adapters on your PC.

To do so, type "NCPA.cpl" in the start menu and press Enter. Then, for any disabled (or greyed-out) adapters, right click them and click "Enable":

After enabling, a Network Adapter will no longer be greyed-out. Also, note that the adapter doesn't need to be connected to the Internet, like in this example, it just needs to be Enabled. Whether the adapter is connected to the Internet or not is unimportant.
