The IIS Aid PHP Installer has been updated to the latest Windows PHP 5.2.9-2 build. This update has only been applied to the 32-bit version, so the 64 bit version is still running PHP 5.2.5. You can download the IIS Aid PHP Installer from here, and you can post support and feature requests along with bug reports in the forums here.
If you are wanting an update to PHP 64-bit, then I suggest having a look at the new PHP 5.3.0 RC1 release as this includes new 64 bit experimental builds of PHP. Please note the "experimental" comment as I would not yet advise you to use them in a production environment.
