Seems like folder permissions not allow server to write compiled volt file in the standard referenced folder (which is the one of the volt source file), if you can't overcome the problem tweaking the permission settings you can instruct Volt to use a different folder (writable by the PHP process / server) for compiled files

$di->set("voltService", function($view, $di) {
        $volt = new \Phalcon\Mvc\View\Engine\Volt($view, $di);
            "compiledPath" => "C:/tmp/voltcachewatever",

        return $volt;

PS: Generally, I suggest to keep htdocs files outside of Windows User folders which has a lot of security constraints.
