phpmyadmin error!! on IIS 6

[dvicil]

Hi I have just configured php and mysql to a Windows 2003 machine. Then I configured Phpmyadmin, I never had a problem before but when I type:
http://localhost/phpMyAdmin-2.5.4

I get an error it says html error 403. That tells me I'm not authorized to see this page.

I also get this error.

Warning: main(./libraries/select_lang.lib.php): failed to open stream: Permission denied in c:\inetpub\wwwroot\phpMyAdmin-2.5.4\config.inc.php on line 436

Fatal error: main(): Failed opening required './libraries/select_lang.lib.php' (include_path='.;c:\php4\pear') in c:\inetpub\wwwroot\phpMyAdmin-2.5.4\config.inc.php on line 436

I'm not sure how to change the include path.I've search everywhere and their explanations have been kind of vague. Any type of help will be good.

It sounds more likely that your IIS doesn't have the necessary permissions to read/execute the requested files/scripts.
