title: VS 2017 NGROK reports not installed after installing
body: <p>Walking through Twilio tutorial which recommends using NGROK with VS2017.
  Find the extension easily enough and installs (have to close VS2017 and reopen) and sure enough the NGROK menu option is clearly "THERE" when I reload the project...yet when I select the menu option (Tools -> Start ngrok tunnel) I get the unfathomable message:

  <p>Ok, so maybe it is not installed "all the way" and so I select YES and shortly receive an null reference exception:</p>

  <p>The instructions to install this is dirt simple...but I seem to be missing something. </p>
