You can run the UI Engine as a standalone Java application with or without a Web browser. The UI Engine must be installed either on the desktop machine or on an accessible network drive.
To run the UI Engine without a Web browser, just start it from a command prompt set in the UIEngine\bin directory. For details, see UI Engine command options.
You can also launch and monitor applications through regular Web browsers. The entire process of launching a ULC application on a server machine, starting the UI Engine on the user's machine, and controlling the started processes is accessible through standard Web-based mechanisms. The ULC HTTP server handles these tasks.
