URGENT - Enabling mcrypt() in PHP 4.3.3 on Windows XP (windows installer

Hi everyone, I recently came across mcrypt(), the PHP encryption system. For the last two weeks I am having trouble getting it to work with PHP. I use WinXP, and the PHP 4.3.3 interpreter. **Note that it came in a installer (php-4.3.3-installer.exe)** What I tried to do was simply uncomment this line in php.ini: Before ---> ;extension=php_mcrypt.dll After ---> extension=php_mcrypt.dll However, when I ran a simple phpinfo() page to see if it was initiated, an error message appeared stating that the dll didn't exist. Strangely, it did exist - in my extensions folder. Please reply ASAP, with a step-by-step guide Cheers, Robin C.
