WampServer

Need to install wampserver on win server 2003, which version to use
Or there is no compatible version

WAMPServer 2.4 is that last version that will run on server 2003.

This is not a WAMPServer limitation. It is because you cannot install the most recent versions of the MSVC Runtime libraries required for the latest versions of Apache and PHP on older versions of Windows.

So this means you cannot install the latest safest versions of Apache and PHP
