Can't enable CURL - WAMP on Windows 7 64 bit - PHP 5.3.13 Apache 2.2.22
no need to take shortcut of installing Wamp, i would suggest to install the Apache,MySql and Php stack individually.
I also came across this curl problem in wamp so i switched to installing them individually. you can follow these links with detailed description and slides to configure all three :-
1. Mysql

2. Apache

3.Php

This is one time process and is standard way to carry out things . You can also look into this(same for Win 7) :-
