Problem in Installing Wordpress

Question

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

Answer 1

What if you uninstall PHP and reinstall it to C:\PHP?

I've seen problems when PHP is installed to a path that includes a space.

Answer 2

What is the path to php_mysql.dll? Is it correct in php.ini?
