2 possibly connected problems:
1. At this point I have a wordpress folder in my web root but when I connect to wordpress/wp-admin/install.php I get a dialog asking to download or open with Notepad. At some point in the fatigue fogged past I did see a page partially addressing this issue, but hey, that was 300 pages ago.

2. Accessing other wordpress php files produces an error message page: ‘Invalid or missing PDO driver’

I am installing a personal blog on localhost & as such don’t need a huge database.
I am trying to install WP using the PDO-sqlite plugin as per https://www.ads-software.com/extend/plugins/pdo-for-wordpress/installation/ which I think I have right.
I am using Vista, Apache 2.2, PHP 5.2
Apache is configured for PHP as a module
php_info() shows:
PDO
PDO support enabled
PDO drivers sqlite2

WordPress V 2.5.1 as specified for this plugin
PHP.ini shows:
extension_dir =”C:\Web\PHP\ext”
[PHP_PDO]
extension=php_pdo.dll
[PHP_SQLITE]
extension=php_sqlite.dll

The PHP\ext folder shows:
php_pdo.dll
php_sqlite.dll

phpinfo() works and shows:
PDO
PDO support enabled
PDO drivers sqlite2

wp-config.php shows:

// ** MySQL settings ** //
    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
    define('DB_CHARSET', 'utf8');
    define('DB_COLLATE', '');
    define('DB_TYPE', 'sqlite');    //mysql or sqlite
    define('SECRET_KEY', 'Dear Diary, what a day it's been'); // Change this to a unique phrase.

    // You can have multiple installations in one database if you give each a unique prefix
    $table_prefix  = 'wp_';   // Only numbers, letters, and underscores please!
    define ('WPLANG', '');
    define('ABSPATH', dirname(__FILE__).'/');
    require_once(ABSPATH.'wp-settings.php');
    ?>

I apologise the the length but felt I neeed to provide as much relevent info as possible.
