TYPO3 Core

PROBLEM:
You make a clean install over Apache/MySQL by downloading 'typo3_src-4.0.2.zip' and 'dummy-4.0.2.zip'. You do everything by the book, but you cannot login to the backend.

Why? Because there is no admin-user in the database. You cannot even create an admin user. Database Analyzer tells that user is created but actually it is not!

SOLUTION:
You are using MySQL 5. You should use MySQL 4, or turn on the MySQL4-mode in MySQL 5. For additional information see:
http://wiki.typo3.org/index.php/Windows#MySQL

AN IDEA:
Please put some kind of warning into INSTALL.TXT that installing over MySQL 5.x doesn't work -- because that is what people are going to download, the newest version.

ADDITIONAL IDEAS:
- Check the MySQL version, warn if MySQL 5 is detected.
- Test the existence of Admin user in the Install tool, warn if none is detected.
