Missing folders

I downloaded a fresh copy of dolphin Dolphin-v.6.1.4-Free, unzipped it, FTP'd and ran install.  During the permission check, only the Folders were listed (did not include the files).  Clicking NEXT displayed all the files that were not modified.  Went back and did them.  Put in the SQL and other parameters.  After the SUCCESSFUL INSTALL page, I received a message saying it can't open the data stream for /ray/inc/header.inc.php.  Come to find out, there is no INC folder in the RAY folder.  I downloaded the Ray-v.3.5.3-Suite-Free to see if there's an INC folder but not there either.

Even the DETAILED Instructions says the following:

chmod -v 666 ./periodic/cmd.php ./periodic/notifies.php ./inc/params.inc.php ./ray/inc/header.inc.php ./ray/inc/cron.inc.php

but ./ray/inc does not exist.

This is fresh from download, no mods, any ideas?  Is this a flaw in the download?

Try looking in the ray/modules/global/inc directory, there should be a header.inc.php file in there.

I'm sure the file exists, the problem is the program and its configuration "out of the box" is looking for it in a different location.  My question are 1) is this normal and, if so, 2) what's the easiest fix?  I could understand if this was an Alpha version or heavily modded, but I don't want to spend countless hours tweaking a fresh software product.  You feel me?
