Error, настраивающий Подвижный на Windows Server 2008

Я хочу настроить Подвижный сервер SC и следовал инструкциям, найденным здесь: http//stackoverflow.com/questions/818571/how-to-setup-mercurial-and-hgwebdir-on-iis

Я проверил все мои настройки многократно и, может казаться, не передаюсь эта ошибка после завершения конфигурации. Любой совет был бы полезен.Спасибо.

 Most likely causes:
The CGI process was shut down or terminated unexpectedly before it finished processing the request.
The CGI process has a flaw and does not return a complete set of HTTP headers.
 Things you can try:
Check the event logs on the system to see whether the CGI process is shutting down unexpectedly.
Troubleshoot the CGI application to determine why it is not sending a complete set of HTTP headers.
