Installation with Filezilla doesn't work for me

Hello!
I followed the very easy steps and uploaded all the content from the wordpress folder. When I then opened the wp-admin.com/install.php link it just showed med this https://imageshack.us/photo/my-images/819/skrmbillede20111011kl12.png
No guide, just some kind of welcome page. I edited the wp-sample-config.php file, renamed it, and uploaded the hole thing again. Same problem.

Thank you in advance!
