You will see an error message when starting HDR Light Studio if the Bonjour service is not found.
Bonjour, developed by Apple, enables automatic discovery of devices and services on a local network using industry standard IP protocols. We use this technology to check that other users on the same network are not using the same HDR Light Studio license. HDR Light Studio requires an active Bonjour service and will not start without it.
To fix the 'Bonjour not found' issue, we suggest restarting your computer and running the HDR Light Studio installer again. This will install Bonjour on Windows computers for you. MacOS computers have it installed by default with the operating system. If you still have issues with Bonjour and it is installed, please contact email@example.com to get help.
