How do I install cURL on Windows? I have been looking for answers for days. Please help.

I have made sure that all required *.dll's are in the \system32 directory(I think?). Still nothing. The extension_dir in php.ini file reads like this (extension_dir = e:\php\extensions) and the windows extension is uncommented and looks like this (extension=php_curl.dll). However, when I look at the PHP info here it does not show anything about cURL being enabled or disabled. Perhaps there is something missing from my php.ini file? Going on 3 days with this problem, I'll have to throw a party to celebrate this accomplishment. hehe I'm still curious on the cURL install? All I've done with the cURL *.zip is unzip the file to a root directory. Nothing has been done with the environment variables. Does PHP require the cURL.exe? Any help would be greatly appreciated.

Thank you,
