Here is the message that I get:

Warning: Cannot modify header information - headers already sent in C:\xampp\htdocs\wiki\includes\Exception.php on line 269

Warning: Cannot modify header information - headers already sent in C:\xampp\htdocs\wiki\includes\Exception.php on line 270

Warning: Cannot modify header information - headers already sent in C:\xampp\htdocs\wiki\includes\Exception.php on line 229 A database query syntax error has occurred. This may indicate a bug in the software. The last attempted database query was: CREATE DATABASE `my_wiki` from within function "MysqlInstaller::setupDatabase". Database returned error "1044: Access denied for user @'localhost' to database 'my_wiki' (localhost)". Backtrace:

Can you help me?

You used the wrong database password when trying to install (Or the username/pass is valid, but the user doesn't have sufficient rights). Using the right password should fix the issue.

I've filed bugzilla:43528 for the error message being too complicated/ugly.
