local MAMP Installation problems

Mamp seems to be working fine, Apache and MySQL are working and I can get to my Mamp homepage. The wordpress folder is in the htdocs folder and I changed the wp-config.php file to match the settings on the Mamp page after making a database (database:wordpress, user:root, password:root, localhost:8889).

However when I go to http://localhost:8888/wordpress/wp-admin/install.php to complete the install it says “not found on this server”. I can’t figure out what’s not working. Thanks in advance for your help.
