Zend Guard not being installed on CWP Multiple PHP configuration

Hi im using 2 versions of PHP (7.2 and 5.6), in the PHP options for PHP 5.6 i have selected to "Install Zend Guard Loader", but even if it is selected and i save changes and restart the server, Zend guard loader is not being installed.



I have search in all folders with no luck , also i have tried to found the files in here with no luck:
5.5 :
/usr/local/zend/5.5/ZendGuardLoader.so (not exists)
5.6
/usr/local/zend/5.6/ZendGuardLoader.so (not exists)

How can i Install Zend Guard Loader without messing up CWP, or where is it being installed?? i need to know the route because a script we are installing ask for the route, thanks. in advance..
