Hi,
- Support for Joomla 2.5 is stopped since the end of 2014. The security holes will not be repaired.
- PHP 5.3.x is obsolete, the last version is 5.3.29 that is also obsolete.
- Apache Version 2.2.17 is obsolete
- MySQL 5.1.53 is obsolete
- WampServer 2.1d 64bit is obsolete and no more supported.
- 64-bit versions of Apache, PHP and MySQL are still considered experimental.
Looks like you purposely choose only old thing with the simple aim of attracting hassle.
Nevertheless, in all cases, especially with Joomla, to avoid certain problems, you must use the VirtualHost:
