how to find if my thingworx is licensed or not

Hi Swetha, did you not have to use license file during installation process? or was it not needed to configure the activation details in the platform-settings.json?As far as I know you may not have to setup license file for trial installation, nevertheless you can navigate to the ThingWorx Composer > Monitoring >  Subsystems > Licensing Subsystems Settings and you can check the licensed features and availability of the entities and their count if its a paid license.

Also as far i see there're also some services within the LicenseSubsystem that can give further detail on your licenses e.g. GetLicenseState to check if a license exist or not.
