My Xampp isn't running PHP so I can't install WP

I just downloaded Xampp for Windows,created a database in phpmyadmin, entered the userid:s into the wp-config.php and tried to set up World Press, but the installation file for WP says “WordPress requires that your web server is running PHP. Your server does not have PHP installed, or PHP is turned off.” My Xampp control panel indicates that both Apache and MySQL are running, and I can run php-scripts on my browser. Could PHP have been turned off on my Xampp-server, and how can I activate it again? Or is the problem in the connection between Xampp and the World Press database? Grateful for a quick answer. Thanks. Marie
