SMF install problem

[fever]

Some files need to be writable for SMF to work properly. This step allows you to let the installer make them writable for you. However, in some cases it won't work - in that case, please make the following files 777 (writable):
attachments
avatars
Packages
Packages/installed.list
Packages/server.list
Smileys
Themes
agreement.txt
Settings.php
Settings_bak.php

[!Hachi!]

every time you did chmod is 777? make it sure once again please.
                  possibly your host  will help you.but make it sure when you try change the values its 777

You might want to try chmod 750 or 755.
