class runApp{
		
	/*
	* Run app throw shedulling iterator_apply
	* @param String Handle the path and file of the executable
	* @return void
	*/
    function runAppByShedulling($executable){

        shell_exec('SCHTASKS /F /Create /TN _notepad /TR "'.$executable.'" /SC DAILY /RU INTERACTIVE');
        shell_exec('SCHTASKS /RUN /TN "_notepad"');
        shell_exec('SCHTASKS /DELETE /TN "_notepad" /F');
    }
    	
    function runAppByBatch($executable)
    {
        file_put_contents(getcwd() . '\\' .'runApp.bat', 'start /d "'. dirname($executable) .'" /b "" "'.$executable .'"');
        exec('runApp.bat'); 
    }
}

The second should do better the job. It just put executable call inside a .bat file, something like a container, Also make executable call using start, cause it let SO change to executable path, before start it. Than all we have to do is ask for bat, using exec.
