Inside the folder that as WordPress, put a folder with all the bbPress files in it. So maybe you have this:

/public/html/wordpress/

add a new folder:

/public/html/wordpress/forum/ (or forums or discussion or bbpress)

then access your new installation at http://www.example.com/forum (or whatever you selected) assuming WordPress is accessible at http://www.example.com/
