Maybe it's a simple problem, but i really don't know the answer.
I have uploaded the files to my webserver, chmod /logs and /temps to 777.
Created a database and user
Loaded mysql.initial.inc in phpmyadmin , no problems.

Now i have to install isn't it?
on my domain, i receive this message on http://mail.domain.com/installer
