Installing WP Locally Using XAMPP

First, I know only a little and here is the installation guide I used successfully:

note: Refresh the page to get rid of the signup.

I ran into the msg “You appear to have already installed WordPress. To reinstall please clear your old database tables first.” My question is where do I go to do this and what bits of code do I need to use?

You might not really need to do that, but you would go to the Xampp Control Panel to access phpMyAdmin and then select the proper database and drop its tables.

Got to step 9.. where I went here (localhost * wordpress *wp-admin *install.php) and entered in the wrong information for username (should have used ‘root’).

Also, it asked me to username/password/email …nothing about my database name, database host or table prefix. Perhaps this was wrong from the begining?

I do the database part by manually setting wp-config.php beforehand, then only need to set my WordPress username, e-mail and password during the actual WordPress installation after going to ‘https://localhost/foldername/wp-admin/index.php’.
