I try to install Wordpress in a Windows Client with WebPI which provided by Microsoft.

I had tostop installation process 3 time and installing PHP and mysql Extention manually. but everytime I continue setup by WebPi andfinally it show me a success message.

But when I try to see installed wordpress in my client I see this

Your PHP installation appears to be missing the MySQL extension which is required by WordPress.

I asked it in StackOverFlow here but I couln't get the right answer.

I install everything in **C:\Program files\** so these are the location

C:\Program Files\MySQL\MySQL Server 5.1

C:\Program Files\Php

C:\Program Files\ext

mysql root password: admin

wordpress database : wordpress

wordpress database password : 123

here is my php.ini
