[Phpmyadmin-devel] windows 2008

I am trying to install phpmyadmin on windows server 2008. PHP is installed properly, PHP is configured properly in IIS7 but when i try to run index.php from the phpmyadmin directory i get the following error:

PHP Warning: require_once(./libraries/common.inc.php) [<a href='function.require-once'>function.require-once</a>]: failed to open stream: Permission denied in C:\Inetpub\wwwroot\phpmyadmin\index.php on line 34 PHP Fatal error: require_once() [<a href='function.require'>function.require</a>]: Failed opening required './libraries/common.inc.php' (include_path='.;C:\php5\pear') in C:\Inetpub\wwwroot\phpmyadmin\index.php on line 34

Can someone please help me? Thanks
