Lost in an Install Loop

[yerg]

Ok so I figured I'd go back trash the lot and begin again

I have the two files LetoDMS_Core-3.3.0.tgz and LetoDMS-3.3.0.tar.gz
I extract them both into the root folder
Visiting domain.com/install/install.php gives the following errors

letoDMS Installation for version 3.3.0

Error
Pear package : Log : Not found
=> Install Pear package 'Log'

Warning
Pear package : HTTP_WebDAV_Server : Not found
=> Install Pear package 'HTTP_WebDAV_Server', if you intend to use the webdav interface

Warning
Zend Framework : Not found
=> Install Zend Framework, if you intend to use the full text search engine

Zend is installed server wide and Pear Log is installed and even though I don't wish to use Webdav or the search engine I check via SSH just in case. All is installed and functioning

So I now set up the database and run the sql and install the tables

Edit conf.Settings and settings.xml files

Browse to install directory and get

Warning: require_once(LetoDMS/Core.php) [function.require-once]: failed to open stream: No such file or directory in domain.com/folder/inc/inc.DBInit.php on line 27

Fatal error: require_once() [function.require]: Failed opening required 'LetoDMS/Core.php' (include_path='/home/24728/data/pear/php') in domain.com/folder/inc/inc.DBInit.php on line 27

Ok so I edit that file and replace LetoDMS/Core.php with the full path to the Core.php file

Now I get the error

Warning: require_once(path/domain.com/Core) [function.require-once]: failed to open stream: Success in path/domain.com/folder/inc/inc.DBInit.php on line 27

Fatal error: require_once() [function.require]: Failed opening required 'path/domain.com/Core' (include_path='/home/24728/data/pear/php') in path/domain.com/folder/inc/inc.DBInit.php on line 27

So again I place the full path in line 27

Now I get

Warning: require_once(path/domain.com/folder/Core/Core.php) [function.require-once]: failed to open stream: No such file or directory in path/domain.com/folder/inc/inc.DBInit.php on line 25

Fatal error: require_once() [function.require]: Failed opening required 'path/domain.com/folder/Core/Core.php' (include_path='/home/24728/data/pear/php') in path/domain.com/folder/inc/inc.DBInit.php on line 25

Ok inc.DBInit.php on line 25 is

require_once($settings->_coreDir.'/Core.php');

So I go back to the conf.Settings file and check line 61

var $_coreDir = "path/domain.com/folder/Core";

All is well

But now I'm stuck .... cannot move forward in any way
All I have is

Warning: require_once(path/domain.com/Core) [function.require-once]: failed to open stream: Success in path/domain.com/folder/inc/inc.DBInit.php on line 27

Fatal error: require_once() [function.require]: Failed opening required 'path/domain.com/Core' (include_path='/home/24728/data/pear/php') in path/domain.com/folder/inc/inc.DBInit.php on line 27

Obviously I'm a dumb sod with all these errors
What haven't I done/not done that is causing this?

I really would love to get this happening but hell its hard at this end
