Can not start website

[nezhalsky]

Hello. Set XAMPP, spread the installation Joomla to ...htdocs/site and when I open in a browser http://localhost/site not start the installation. Writes:
Access forbidden!

You don't have permission to access the requested object. It is either read-protected or not readable by the server.

If you think this is a server error, please contact the webmaster.

Please, whats wrong?

Thank You
