I am surprised that I have to do that.
Anyway I did what you suggested.
In the virtual directory I put /http://localhost:2558/
For the Port to bind web server I put in one of the port numbers that came back from that command you gave me.
Now I get a launch. The error message on the launched web page is; HTTP Error 400 - Bad Request.
