Big help with installation

Hello guys created the mysql database and user and uploaded my file and got this message when i tried to access the install/index.php :  internal server error   or server missconfiguradtion. Can someone help me please?

Did you follow these instructions? --> HERE

yes the first part. But i was wondering if there was a file in which i had to put database username and password

Open .htaccess file in the root and comment out or remove the #php_flag register_globals Off line.

Well once into the Installation..YES there is a section which introduces SQL Database values for proper installation and configuration.

If your server is being flag because you have Registered Global_ON rather then OFF I suggest you open the PHP.INI file and TURN OFF Registered Globals. I would also review to make sure you have other PHP features properly set. Those aspects are covered in Installation like above.
