May be this helps you.
Just check if you have a file named default.settings.php at the path <drupal installation->sites->default->default.settings.php
Also ensure that the same file has read write permissions. Once the installation if dome you can change it back to read only mode.
The directory sites/default needs write access by the httpd server as well.
