php - Running WScript within Laravel -

i'm trying spawn background python program php. can locally using php can't work through laravel/iis. think due security setting can't figure out , i'm not sure if laravel or iis blocking it.

when try run through laravel, doesn't throw errors , $result = 0. it's nothing happens.

i'm using php 5.5 x86 nts, iis 7, , laravel 5.

php code i'm using in both situations (locally, through laravel/iis):

<?php      $wshshell = new com("wscript.shell");     $result = $wshshell->run("python c:\dashboard\public\python\dummy.py", 3, false); ?> 

dummy.py writes timestamp file.

any ideas?
