Hey @user25

I do not understand what you mean by “I have a localhost server running but i’m actually using it in NWJS and not the localhost and its not working either”.

The license key domain should point to the domain of your production application - you do not need to set it to localhost. Valid license keys will always work on localhost for development purposes, regardless of the domain set.

Thanks,  
Logan
