Installing Wordpress on Windows 8 using XAMPP but PHP not running

[admin]

I'm Windows 8 user who wants to install Wordpress.

I'm using

XAMPP

and have checked that my XAMPP is working. I also have created a database on MySql and set up the

wp-config.php

with the database details I have created before.
But every time I click the wp-admin/install.php, I get this error :

<blockquote>
Error: PHP is not running
WordPress requires that your web server is running PHP. Your server does not have PHP installed, or PHP is turned off.
</blockquote>

I'm using mySQL database, and database name is wordpress. <br />
This is my config :

<blockquote>
// ** MySQL settings - You can get this info from your web host ** //
/** The name of the database for WordPress */ define('DB_NAME',
'wordpress');

/** MySQL database username */ define('DB_USER', 'root');

/** MySQL database password */ define('DB_PASSWORD', '');

/** MySQL hostname */ define('DB_HOST', 'localhost');

/** Database Charset to use in creating database tables. */
define('DB_CHARSET', 'utf8');

/** The Database Collate type. Don't change this if in doubt. */
define('DB_COLLATE', '');
</blockquote>

I still get the error, need some help.
