[thelogh]

I have installed to my site test with joomla 2.5.24 PHP 5.4.19 and virtuemart 2.6.8 the new version 2.9.9a.
The installation of the componet and aio is without error, but when on the menu select Virtuemart-aio give me  this error...

Warning: require_once(/home/content/43/11132643/html/siti/alldiscoveries.XXXX/administrator/components/com_virtuemart_allinone/classes/controller.php): failed to open stream: No such file or directory in /home/content/43/11132643/html/siti/alldiscoveries.XXXX/administrator/components/com_virtuemart_allinone/admin.virtuemart_allinone.php on line 116

yes - the AOI will probably be depreciated in the final release - the menu does nothing now - there is no AOI comp
the menu is just a "left-over"
