If you have a problem after or before installing the component please read our troubleshooting page for the February 2013 releases of our components. Do note that these issues are only likely to affect users with old versions of PHP, Joomla! and/or very old versions of our components.
This version requires PHP 5.3 or 5.4. The rationale behind this is explained in our statement of mid-February 2013. It won't install on hosts running PHP 5.2 or earlier. Moreover, due to the necessary Joomla! API changes found only in Joomla! 2.5.6 or later, this version will not install on Joomla! 2.5.5 or earlier versions. In any case, it will tell you exactly why it cannot be installed (minimum PHP or Joomla! version not satisfied).
