Hi Uhreskov,
What I suggest is that you install WAMPServer 2.4. This is the last version of Apache/PHP that will run on Windows XP and comes with PHP 5.4.16 and Apache 2.4.4
Do not just install WAMPServer over the top of an existing WAMPServer. Before you attempt to upgrade PLEASE read this post
Installing a new release of WAMPServer this should help you do the upgrade without loosing any of your existing sites/databases
As you have such an old version of WAMPServer, switching versions of Apache and PHP will probably not work very well. Since your version, many changes in Compiler used to create Apache and PHP have happened, and this makes the switching process more complicate unfortunately
