Cannot install past license screen

Hi All,

I am trying to install Sugar Enterprise 7.8.2.0 in the server.I can access the install screen but i can not click Next button "License Acceptance" page.

When i click,below is what i get in browser console

install.php:98 Uncaught ReferenceError: YAHOO is not defined

In install.log

installerHook: Could not find custom/install/install_hooks.php

I referred below Cannot install past license screen  But didnot help

Thanks
