Install Zend Optimizer on Windows 2003/IIS6

Download the latest Zend Optimizer

Chose the correct web server

Locate PHP.ini file if you install php 4 and 5. after the installation check the php 4's php.ini file and copy and paste the last entry into php 5's php.ini file

Choose the webroot folder (if your webroot folder is not the Windows's default, for example, if you use Helm control panel and you have your domains files host on second hard disk ( D:\domains ) You should still use the default C:\Inetpub as the webroot folder.

Finishing up ( you should see this screen before Zend Optimizer install all the necessary files )

Now, let's run phpinfo() function to check if Zend Optimizer is installed or not.

Problem: PHP 5 configuration file (php.ini) path is set to PHP 4

If you have both PHP 4 and 5 installed on the same server you may have the problme of PHP 5 using PHP 4's php.ini file

All you have to do is delete the registery entry in Windows registery. The entry is locate at HKey_Local_Machine -> PHP Look for inifilepath entry and delete it.

Look into the PHP 4's php.ini file. At the very end you will see the Zend extension entry. simpl copy and paste it into PHP 5's php.ini file.

That's it!
