Mysql 5.1 telepítésnél a lenti hibát kapom az apply sequrity setting fülön. Miért? Mit csináljak?

The sequrity setting could not be applied to the database because the connection has failed with the following error.

error Nr. 1045

Access denied for user 'root'@'localhost' (using password: YES)

If a personal firewall is running your maschine, please make sure you have opened the TCP port 3306 for connection. Otherwise no client application can connect to the server. After you have opened the port please press (Retry) to apply the security settings.

If you are re-installing after you just unistalled the MYSQL server please note that the data directory was not removed automatically. Therefor the old password from your last installation is still needed to connect to teh server. In this case please select skip now and re-run the Configuration wizard from the start menu.
