ASP.NET Project running an exe on local host level but do not when same project runs after virtual directory.

I have an asp.net project in which thereis a button on which some exe runs which resides in my computer only using System.Diagonistics.Process.Start("path of exe");

When I am running project on localhost through .net run utility then on pressing that button exe runs smoothly but after making virtual directory of the same project and then if i run that project by typing complete address in address bar then that particular button is not performing its function thus exe is not running .

i have already tried to display the whole path in a label on both levels : localhost and after making virtual directory as well........in both cases complete path is visible and matches also but exe doesn't run after making virtual directory and on internet level...

need help in this aspect.

 

thanks in advance
