How do I launch a .exe file with a button click from a menu inside a Zinc 4.0 built flash project

Question

I am current working on a project to place a Zinc 4.0 built flash menu on a CD. One of the buttons on the menu needs to open a external catalog that is a .exe file. I was able to use the fscommand scripts to get this to work in a flash projector. But I wanted some more options in the design of the windows itself so I ran it through Zinc 4.0 instead. Now the file no longer executes on the button click.

I tried some of the some Zinc 4.0 scripting and it still does not work.

This is the code snippet I am currently using.

view_btn.addEventListener(MouseEvent.CLICK, openCat);
function openCat (e:MouseEvent):void {
fscommand("exec",mdm.Application.path+"cellrun.exe");
}

Any suggestions or ideas ?

Thank you
