Assembly of the Zend Guard loader

Installation of Zend Guard Loader
My Apache is httpd-2.2.22-win32-x86-openssl-0.9.8t,
PHP is php-5.3.5-win32-vc6-x86
Zend is zendguardloader-php-5.3-windows.
I copied the ZendLoader.dll into the PHP ext directory, and then php.ini the following changes
zend_extension= "G:/wamp/php5/ext/zendloader.dll"
Zend_loader.enable=1
zend_loader.disable_licensing = 0
Zend_loader.obfuscation_level_support = 3
Restart the server is not successful, I find on the Internet is also the above method, please the great god advice.

Now that you're sticking with this, you can take a look at the wrong things when you start Apache, or you can send the error log up to look for reasons.
