XF 1.3 Can't install

can't install

im quite sure I did this correctly but i just keep getting the 404 file not found message

http://www.example.com/community/install/index.php (sub my domain)

i created community folder uploaded files--set the permissions on data and internal_data folders (recursive)

it just doesn't work--double checked on my cpanel-everything there

i had just installed phpbb3 a few days ago so i know it should work

Ok got it--host added a directory between domain and my files--added that to the url and can install
