Already installed error

OK, so I ma trying to install WP on my laptop for development purposes, and am not having much success; I keep getting:-

wp-config.php file. I need this before we can get started. Need more help? We got it. You can create a wp-config.php file through a web interface, but this doesn’t work for all server setups. The safest way is to manually create the file.

Create a Configuration File”, “WordPress › Error”); } require_once(‘../wp-config.php’); require_once(‘./includes/upgrade.php’); if (isset($_GET[‘step’])) $step = $_GET[‘step’]; else $step = 0; function display_header(){ header( ‘Content-Type: text/html; charset=utf-8’ ); ?> >

‘.__(‘Already Installed’).’

‘);} switch($step) { case 0: case 1: // in case people are directly linking to this display_header(); ?>

‘.__(“ERROR: you must provide an e-mail address.”).’
‘); } else if (!is_email($admin_email)) { // TODO: poka-yoke die(‘

‘.__(‘ERROR: that isn’t a valid e-mail address. E-mail addresses look like: [email protected]’).’
‘); } $wpdb->show_errors(); $result = wp_install($weblog_title, ‘admin’, $admin_email, $public); extract($result, EXTR_SKIP); ?>

‘; ?>

Now a) I have made the wp config file, and b) I doi not have WP already installed. I have made several attempts now and am still no closer to getting it up and running, and searching seems to provide no answers either… If there were a handy brick wall I would be banging my head against it!
