Hi Everyone

After many frustrating weeks and several attempts at installing Zen Cart on a computer running windows 7, yesterday I installed XAMPP (1.7.4) and Zen Cart (1.3.9h) on a clean (nothing else on it) computer running XP with service pack 3.
The installation went well with no problems until I encountered the "Enabling cURL support in PHP" instructions. I tried to edit the file <xampp-home>/apache/bin/php.ini but the php file was missing completely.

I did manage to import the php file from another computer (the one running windows 7) but after editing it, it had no effect.

I continued with the install and everything else went well but what have I done wrong, and how can I fix it?
