A: Dear Rik, thanks for the question

Just to clarify, for level 4 and higher is the license to resell executables unlimited?
>>> Yes that is correct

For example, if I have Level 4 for 50 Machines, can I only sell 50 executables or is the number of machines unrelated to our reselling rights?
>>> The Number of Machines is the number of Devices on which you can activate RTILA Studio using your main license at one given point. You can generate sub-licenses (called Team Activation URLs) and share them with your teams/staff so they can activate their RTILA Studio on their computers without the need for you to reveal your main license.
