title: PHP CURL not loading in WAMP after upgrading PHP from 5.3.4 to 5.3.22
body: <p>I have the exact same issue as <a href="https://stackoverflow.com/questions/10939248/php-curl-not-working-wamp-on-windows-7-64-bit">PHP cURL not working - WAMP on Windows 7 64 bit</a> </p>
  
  <blockquote>
    <p>CURL doesn't load at Apache restart, with message: "PHP Startup: Unable to load dynamic library 'c:/wamp/bin/php/php5.3.22/ext/php_curl.dll' - The operating system cannot run %1.\r\n in Unknown on line 0"</p>
  </blockquote>
  
  <p>Except that I am not installing 5.3.13 as in the other thread but I am attempting to upgrade PHP in an existing WAMP installation from 5.3.4 to 5.3.22, both x64 VC9 TS on a Win 2008R2 64 bits, running Apache 2.2.4 x64.</p>
  
  <p>I did the following steps: </p>
  
  <ul>
  <li>stopped Apache</li>
  <li>unzip php5.3.22 in /wamp/bin/php5.3.22;</li>
  <li>updated php.ini, httpd.conf and the 2 Wamp config files to point to the new PHP version; </li>
  <li>updated php5ts.dll and php5isapi.dll in Apache\bin with the new ones</li>
  <li>updated Windows PATH to point to php5.3.22 folder instead of php5.3.4</li>
  <li>restarted Apache -> CURL load error message </li>
  </ul>
  
  <p>I could try most of the answers provided in other threads except the one from Matthieu:</p>

    <p>Go to <a href="http://www.anindya.com/php-5-4-3-and-php-5-3-13-x64-64-bit-for-windows/" rel="nofollow noreferrer">http://www.anindya.com/php-5-4-3-and-php-5-3-13-x64-64-bit-for-windows/</a> and download the curl version that corresponds to your php version under "Fixed curl extensions:".</p>
  </blockquote>
  
  <p>...as there is no "Fixed curl extension" for 5.3.22 in Anindya's site.</p>
  
  <p>Does anyone know if there is need or not for a "fixed curl lib" after 5.3.13? and where I can find it?</p>
