This will walk you through a mock device setup so you can emulate a Thunder Laser in your LightBurn trial. When installing LightBurn for the first time be sure to select Install FTDI Drivers so they will already be loaded. Once you get your Thunder Laser you can delete the mock device and run the Device Wizard (if connected USB) and it should find and install your Thunder Laser automatically. 

You can get LightBurn Here: LightBurn Software
