joomla api - installing the libraries folder

if the joomla libraries folder is missing from a joomla site, is it possible to install it simply by copying and pasting the libraries folder from another joomla installation? or is there specific procedure. i tried copying and pasting so that i have access to the JApplicationHelper class, and I get the following error:
Fatal error: Class 'JApplicationHelper' not found in <appserv>\administrator\components\com_rates\toolbar.rates.php on line 3. The code that calls the function is attached.
<?php
 
require_once( JApplicationHelper::getPath( 'toolbar_html' ) );

Open in new window

Web applications are systems that run in browsers that perform functions normally associated with other client-based programs. One of the most commonly used web applications is email; instead of downloading individual emails to a local machine, the data is shown through a website. Other examples of web applications are collaborative systems like a wiki or an online game.
