title: How to install Zend Guard Loader on Xampp
body: <p>I have been using a software which files are encoded by Zend Guard. Since PHP 5.3 + versions don't support Zend Optimizer hence I have to <strong>install Zend Guard Loader</strong> to run that application on my windows xampp installation.</p>
  
  <p>I downloaded Zend guard loader and copied to xampp folder.Then I edited the following lines to php.ini file.</p>
  
  <pre><code>zend_extension ="E:\xampp\ZendGuardLoader\php-5.4.x\ZendLoader.dll"
  zend_loader.enable=1
  </code></pre>
  
  <p>Then restarted the xampp but it was giving <strong>php5.dll missing error</strong> then I downloaded php5.dll file from internet and uploaded to xampp/php folder and edited following file
  <strong>xampp\apache\conf\extra\httpd-xampp.conf</strong> here I edited this line</p>
  
  <pre><code>LoadFile "/xampp/php/php5ts.dll"
  </code></pre>
  
  <p>to 
      LoadFile "/xampp/php/php5.dll"</p>
  
  <p>then the php5.dll error gone and the following error occurred:</p>
  
  <blockquote>
    <p>"the procedure entry point zend_new_interned_string could not be located in the dynamic link library E:\xampp\ZendGuardLoader\php-5.4.x\ZendLoader.dll"</p>
  </blockquote>
  
  <p>When I tried to search on internet then found that this is the issue with <strong>'Thread Safety'</strong> is enabled in xampp php. I don't know how to disable 'Thread Safety' or how to use <strong>'Non Thread Safety'</strong> php version with xampp.</p>
  
  <p>Please help me to <strong>install Zend Guard Loader</strong> on Windows 8 os Xampp 1.8.1 with php 5.4.x</p>
