Hi Lascelle,
As far as I am aware there are no 64bit compilations of PHP5.3.anything so the simple answer is you cannot.
See here for downloadable PHP windows builds [
windows.php.net]
In WAMPServers configuration PHP runs as an Apache module, so Apache and PHP have to both be 32bit or 64bit compiles.
You would have to install the 32bit version of WAMPServer. It works just fine on a 64bit Windows.
Now you have a few options here :-
You can actually install the 32bit WAMPServer and the 64bit WAMPServer on the same machine as long as you install then in different folders i.e. \wamp\ and \wamp32\ for example or one onto C:\wamp and one onto D:\wamp\
As long as you dont run them both at the same time as among other reasons both Apache's will be trying to use port 80Or
The simpler route would be to uninstall the 64bit WAMPServer and install the 32bit WAMPServer. Although this may depend on what you already have running on the 64bit version!
Luckily PHP5.3.28 does have have the linkages to Apache 2.4 so you would not need to install another older version of Apache. Coinsidentally I am using it now myself for a specific project, but I use 32bit WAMPServer for this very reason.
Let me know which option you think you would prefer and I can help with what you will need to doIf you decide to go for the throw away 64bit and install 32bit here is a document you shoudl read, that tells you how to uninstall WAMPServer without actually removong any files from disk so you have a backup of what you corrently have to move ot to the newly installed version of WAMPServer.
