Please follow the below steps to install/update Ioncube loader on a Windows Plesk server. Please disable and backup the current ioncube loader files in case of updating ioncube. This would be helpful to revert the changes.
1). Firstly create an php info page to know the path of PHP loaded configuration.
2). Now download the latest MSI installer of IonCube Loader from "
http://www.ioncube.com/loaders.php".
3). Select the appropriate versions (32 or 64 bit version) of the package. Select the package Windows non-TS Loaders only for the windows systems where the thread safety option is in disabled status (which can be found from info page)
4). Run the Setup and follow the next steps.
5). When installer prompts for the Installation type, select the option “Install to this machine” and specify the correct path of plesk php (say like %plesk_dir%\Additional\PleskPHP5\extensions) where %plesk_dir% is your Plesk installation directory.
6). Proceed to next step and complete the installation.
7). Check if the ionCube libraries (.dll files) are saved on the Plesk PHP path. (It would be in %plesk_dir%\Additional\PleskPHP5\extensions\ioncube folder).
8). Now open respective php.ini files (check your PHP versions) and insert the path to IonCube Loader's Library.
For example edit PHP 5.x php.ini file, add the following extension at the end -
zend_extension_ts = %plesk_dir%\Additional\PleskPHP5\extensions\ioncube\ioncube_loader_win_5.x.dll
9). Make sure to give the correct php versions and library file in the php.ini file. If you are using PHP 5.4 open the respective php.ini file and give the ioncube loader as ioncube_loader_win_5.4.dll.
Also replace %plesk_dir% with your plesk path.
10). Restart the IIS. Now check the info page for the changes.
That's all. Now check your phpinfo page to see for the updated version.
