If you want return value use 'nsIProcess' :

var file = Components.classes["@mozilla.org/file/local;1"]
                     .createInstance(Components.interfaces.nsIFile);
file.initWithPath("c:\\myapp.exe");
var process = Components.classes["@mozilla.org/process/util;1"]
                        .createInstance(Components.interfaces.nsIProcess);
process.init(file);
var args = ["argument1", "argument2"];
process.run(true, args, args.length);
var retVal=process.exitValue;
