Keep this data safe to use them to log-in to your own Customer Area in the Support Center.
From your Customer Area you can also download your license file(s) and the corresponding NoMachine software package.
The Terminal Server Node subscription has only node.lic.
First upload the key.tar.gz archive containing your license file(s) to the host machine. You must have administrative privileges to be able to activate a license.
Extract the archive: depending on the product you will have one or two license file(s).
Activate all of them by repeating instructions below for each *.lic file.
