[Solved] Run external program with Event Scripter

Hi, I would like to run an .exe after a download finishes, for example putty, but this code does not work in Event Scripter. What I am doing wrong:

var oShell = new ActiveXObject("Shell.Application");
var commandtoRun = "C:\\putty.exe";
oShell.ShellExecute(commandtoRun, "", "", "open", "1");

Error: ActiveXobject is not defined

Thanks
