Example of launch?

[QAscoop]

rdp({
    address: hostname,
    username: user,
    password: password,
    launch: '%windir%\\system32\\notepad.exe'
  }).then(function() {
       console.log(' RDP CONNECTION ENDED!');
  });

This code does not execute Notepad. Hardcoding the path doesn't change the behavior. The rdp connection happens but Notepad doesn't get executed.
Any help, documentation will be appreciated.
