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.

The program installs as a new button in the IE toolbar (as well as a new menu item under "Tools"). Just hit the "Advanced Control" button and it pops up a dialog (you must select the script *.vbs/*.js file from {app}\scripts directory).
