Problems with permission

I have a server where 5 sites are hosted. One of them has a system where you download a file that is in the hosting of another site, but of a same server. The file is there, but at the time of download an error appears.

If I change the path of hosting the site itself it can download the file, but when it is from another place it does not download.

The code:

$patch = 'c:\inetpub\vhosts\portalemme2.com.br\web\assets\agencia_online\pedidos\'.$pedido->link_arquivo;

try{
    fopen($patch, 'r');
}  
catch(Exception $e) {
    var_dump($e);
}

If I change the patch it works.

Erro:
