Magento - Complains missing InnoDB when it is available

Navigate within your Magento Folder

Replace:

public function supportEngine()
    {
        $variables  = $this->_getConnection()
            ->fetchPairs('SHOW VARIABLES');
        return (!isset($variables['have_innodb']) || $variables['have_innodb'] != 'YES') ? false : true;
    }

with

public function supportEngine()
    {
        $variables  = $this->_getConnection()
            ->fetchPairs('SHOW ENGINES');
        return (isset($variables['InnoDB']) && $variables['InnoDB'] != 'NO');
    }
