You should have a folder like
C:/XAMPP or similar, inside that folder should be a htdocs folder
Create a new folder inside htdocs and call it vb
Then you need to import your database using phpMyAdmin (go to
http://localhost and click the PhpMyadmin link on the left)
Then edit your htdocs/vb/includes/config.php file to reflect the new database.
To access your vb go to
http://localhost/vb from your browser
You don't have to import your database, you can start from scratch if you want.
