What about trying XAMPP 1.5.4 ? It comes with: Apache 2.2.3 MySQL 5.0.24a PHP 5.1.6 & PHP 4.4.4 phpMyAdmin 2.8.2.4 FileZilla FTP Server 0.9.18 OpenSSL 0.9.8c
This update will come as soon as I have time for it, I hope this week end. I started last week end but didn't find the time to finish. Maybe PHP 5.2.0 will be out until then???
