"Archive does not exist" installing order export addon

Trying to install the export order addon and get: "Archive does not exist" trying to install from Joomshopping administrator/index.php?option=com_jshopping&controller=update or from the Joomla installer.
Trying to manually upload (which succeeded) and run update.php which comes in packege and get:
Fatal error: Class 'JFactory' not found in /public_html/update.php on line 8
Joomshopping 4.5.0 and Joomla 3.3.1
