Zend Guard Loader (no replies)

Hi! I need to use Zend Guard Loader in a website. The web app I use asks me this:
"PHP 5.6 and Zend Guard Loader activated".

I currently use Wamp with Apache 2.4.23, Php 5.6.25 and MySql 5.7.14 and downloaded Zend Guard Loader for Php 5.6 at: [www.zend.com]

extracted the rar into C:/wamp64/bin/php/php5.6.25/ext/ folder, so final path is:
C:\wamp64\bin\php\php5.6.25\ext\zend-loader-php5.6-windows-x86

then added into php.ini file:

zend_extension=C:/wamp64/bin/php/php5.6.25/ext/zend-loader-php5.6-windows-x86/ZendLoader.dll
zend_extension=C:/wamp64/bin/php/php5.6.25/ext/zend-loader-php5.6-windows-x86/php_opcache.dll

zend_loader.enable=1
extension=ZendLoader.dll
opcache.enable=1

Going to phpinfo I see Zend Engine 2.6.0 (with Xdebug 2.4.1) but nothing for Zend Guard Loader.
The web app throws me the error: Error! Zend Guard Loader Not found.

What am I doing wrong?
