ProjectGuide and Shell command

[Yashr]

Hello:

I am trying to customize Project Guide (html and javascript). I need to have
a link to an external application(exe). The shell command works fine on a
regular html page. But, when I add it to Project Guide, I am getting
'Permission Denied'.
Any suggestions/help is appreciated? We are using Project 2003/server.
The code I am using is


var oShell = new ActiveXObject("Shell.Application");
var commandtoRun ="C:\Test_VB.exe";
var commandParms = "/APP \"Test\"";
oShell.ShellExecute(commandtoRun, commandParms, "", "open", "1");

Thanks
Yashr
