Installation problem sophimail can't install need help !

[RedJohn14]

Hello,

I load last GitHub Version of sophimail and try to install it but have the following error:

If I got to the server IP it will redirect me to http://localhost/login

But I get 404 Not found. I also looked into the webroot folder there is NO login folder or login.php or login.html file.

If I open the URL http://localhost/webroot I have this error message:

Any idea what I can do now? I found no good looking Postfixadmin Interface please help!
