XAMPP (PHP Version 5.2.9) server WordPress installation problem

I have a strange problem with my server.
I installed apache by XAMPP (PHP Version 5.2.9). In the server i tried to install my new WordPress project but while i browse the URL it just shows full file directory. Even if after clicking the index.php it still redirected to the same directory/root directory. I manually installed the worpess project and admin is workingin fine. I can login and make changes.

In the same server, two other domain already located those are CI(codeigniter) sites.
