You need to enable the open_ssl extension on your PHP.ini
Open your PHP.ini , search for this line
;extension=php_openssl.dll
Remove the ; before the line , save the file and restart your webserver and you are good to go.
How to find the right php.ini ?
Create a simple test file like test.php, add <?php phpinfo(); and execute it. Search for Loaded Configuration File line and see the path next to that line.

1Instead of using `phpinfo()` only to find what is the loaded php.ini file path, I would consider using `php_ini_loaded_file()` function (as of PHP 5.2.4) – barell Mar 01 '14 at 15:46
