I am installing SugarCRM 6.5.x version on ubuntu 12 with PHP Version 5.5.6 on lampp.
I am getting error as ..installerHook: Could not find custom/install/install_hooks.php
I have given 777 permission recursively to folders but no success. Also check install_hooks.php but could not find this file.
However installation works on windows (xampp with PHP Version 5.5.9 ) and web hosting on centOS linux.
-Thanks & Regards,
I am doing my best to help and support,sorry in case my suggestion do not help.
