I bought you a module Prestashop Openerp Connector. 
During the installation of OpenERP, an error occurs and the installation does not occur.

OpenERP Warning

Error

You try to install module 'prestashop_openerp_connector' that depends on module 'account_cancel'.
But the latter module is not available in your system.

Is it possible to establish a link between OpenERP Prestashop?
