Advanced Script Host(engine.exe) enables you to run scripts from Windows. Engine.exe provides any dialog window for accessing from script. Whether you use WScript.exe or Engine.exe, you still run the scripts in the same manner. The difference is only in the object model. You can use methods and properties objects: Window, TCPIP, System, Plugins. You will use the extension .w_js(JScript) or .w_vbs(VBScript) for advanced scripts.
