Any suggestions on how I can get Joomla working?

I successfully installed XAMPP on my C-drive. After downloading Joomla, I unzipped it into www\xampp\htdocs\Joomla.

From my webbrowser at http://localhost/xampp/joomla, I return the following error:

Object not found!
The requested URL was not found on this server. If you entered the URL manually please check your spelling and try again.
If you think this is a server error, please contact the webmaster.
