WAMP and cURL on Windows 7 64bit
Just this week I was supporting a collegue of mine where he has WAMP installed on his Windows 7 (64bit) machine but had issues using cURL with a twitter plugin he was working on.
After enabling PHP_CURL via WAMP, locating all the php.ini files that might need to be updated, etc, a simple solution was to go to this website, download the cURL dll based on your PHP version and restart WAMP. Everything working as normal.
