title: PHPExcel ZipArchive not found
body: <p>I've just downloaded PHPExcel package and I tried to import an Excel spreadsheet, but all I get is an error <code>ZipArchive not found</code>. I work on Windows, but server is on Linux. I checked <code>php.ini</code> to see if php_zip is disabled, but it wasn't even there.</p>
  
  <p>I tried  installing it with PECL: <code>$ pecl install zip</code></p>
  
  <p><code>No releases availble for package "pecl.php.net/zip"
  Cannot initialize 'channel://pecl.php.net/zip', invalid or missing package file
  Package "channel://pecl.php.net/zip" is not valid
  install failed</code></p>
  
  <p>And also <code>pear install zip-1.10.2.tgz</code> but recieved pretty much the same message.</p>
  
  <p>I don't have root permission to the server, maybe that's the case? Anyways, could you help me with this?</p>
