Couple of problems I can see there. First, you say you did not delete the earlier install? Best to do that. In fact, delete the current one too and start over with a clean, empty, fresh folder.
Second, you say there is no configure.php file in /includes/? That file is called dist-configure.php in the downloaded file set. You're supposed to rename it to configure.php at some point during the install. You'll be prompted to do so. (There's a similar one in /admin/includes/ which is handled the very same way.)

I got everything to work, finally.
