Hello, your documentation states that the emulator must be extracted to the path ‘LG_WEBOS_TV_SDK_HOME/Emulator’, but this is incorrect. It actually needs to be extracted to ‘LG_WEBOS_TV_SDK_HOME/TV/Emulator’.
Please uninstall old webOS TV SDK and use webOS Studio extension. Environment variables are no longer needed. You can refer to Prepare for installation. Thank you.
