не удалось установить патч magento 6788

Я пытался установить новое исправление magento 6788 на свой Magento CE1.6.1.0, но я не могу применить его успешно из-за следующих ошибок:

Checking if patch can be applied/reverted successfully...
ERROR: Patch can't be applied/reverted successfully.

Я заменил два сбойных файла (.htaccess и Sales / controllers / DownloadController.php) исходными файлами magento, но все еще получаю ту же ошибку.

Пожалуйста, дайте мне несколько идей о том, почему это происходит.

Спасибо.
