PHP problem in Browser

I know this is posted in the past, however I haven’t been able to find a post that helps my case. I am adding wordpress to my site for the first time. I use IX WEBHOSTING and created a database, the host company said everything is set up fine when I spoke with them.

Once I upload everything using FTP into a directory titled blog, I go to

https://virginiadesigncompany.com/blog/wp-admin/install.php

It asks to save the file or open it notepad, won’t let me open in Firefox or IE. how can I view the live website? when I click on install.php from my computer saids “already installed… with a bunch of gibberish”

If I need to provide more information I can, please help. Thanks!

Here is my setup:

<?php
// ** MySQL settings ** //
define(‘DB_NAME’, ‘slepper_wp’); // The name of the database
define(‘DB_USER’, ‘slepper_blog’); // Your MySQL username
define(‘DB_PASSWORD’, ‘xxxxxxxx’); // …and password
define(‘DB_HOST’, ‘mysql9.ixwebhosting.com’); // 99% chance you won’t need to change this value
define(‘DB_CHARSET’, ‘utf8’);
define(‘DB_COLLATE’, ”);

// You can have multiple installations in one database if you give each a unique prefix
$table_prefix = ‘wp_’; // Only numbers, letters, and underscores please!

// Change this to localize WordPress. A corresponding MO file for the
// chosen language must be installed to wp-content/languages.
// For example, install de.mo to wp-content/languages and set WPLANG to ‘de’
// to enable German language support.
define (‘WPLANG’, ”);

/* That’s all, stop editing! Happy blogging. */

define(‘ABSPATH’, dirname(__FILE__).’/’);
require_once(ABSPATH.’wp-settings.php’);
