oShell.ShellExecute problem

Hi,

I want my php script to execute an exe file at the client's machine, i use oShell.ShellExecute() (activeX) to call the exe file, but it display an error msg saying permission denied. I suspect this because of the windows security updates that disabled the oShell.ShellExecute() fucntion.

Here is my code,
      <script language=\"JavaScript\"  type=\"text/javascript\">
        function executeCommands()
         {
        // Instantiate the Shell object and invoke its execute method.
      
          var oShell = new ActiveXObject(\"Shell.Application\");
      
          var commandtoRun = \"C:\\dial.exe\";
            var commandParms1 = document.dialform.CRMID.value;
            var commandParms2 = document.dialform.CallNo.value;
      
            var b = commandParms2 + \",\" + commandParms1;
      
       // Invoke the execute method.  
           oShell.ShellExecute(commandtoRun, b,\"\", \"open\", \"1\");
        }
      </script>

<input type=Button name=Button2 value="Call Now" onClick="executeCommands(' + hasPARMS + ')">
