[Typo3-install] Installation Problems

[Michael B]

I have copied the Typo3Source and the "DummySite" to a directory on the
server.

I have used the install tool and it does't show any errors.

When I enter the backend, two things happen:

1. I do not know what login and password to use. I see no form in the
install tool which sets up the login... Which login and password should I
use? Where do I set the login? Somewhere in the files? I'm confused.


2. I get errors on the backend page:
