2.1 “NEW” Install Problems

I am doing a new install (not upgrade) of 2.1 on my laptop.

I get the below error at the config file stage when I input this address in my browser (IE):

http://localhost/wordpress/wp-admin/install.php%20/

This is the error:

define(‘DB_NAME’, ‘wordpress’); // The name of the database define(‘DB_USER’, ‘root’); // Your MySQL username define(‘DB_PASSWORD’, ”); // …and password define(‘DB_HOST’, ‘localhost’); // 99% chance you won’t need to change this value
Warning: require_once(ABSPATH/wp-admin/admin-functions.php) [function.require-once]: failed to open stream: No such file or directory in C:\xampplite\htdocs\wordpress\wp-admin\upgrade-functions.php on line 5

Fatal error: require_once() [function.require]: Failed opening required ‘ABSPATH/wp-admin/admin-functions.php’ (include_path=’.;C:\xampplite\php\pear\’) in C:\xampplite\htdocs\wordpress\wp-admin\upgrade-functions.php on line 5

Any Ideas?

Thanks,

Ken
