就是最後的Apply security setting過不去
提示：
The security settings 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 on your machine, please make sure you have opened the TCP port 3306 for connections. 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 uninstalled the MySQL server please note that the data directory was not removed automatically. Therefore the old password from your last installation is still needed to connect to the server. In this case please select skip now and re-run the Configuration Wizard from the start menu.
解決方法：
1, 卸載MySQL
2, 刪除目錄 C:\Documents and Settings\All Users\Application Data\MySQL
3, 重新安裝MySQL 就好了
如何你C:\Documents and Settings\All Users下沒有Application Data文件夾，選擇：工具——文件夾選項——查看——選擇顯示所有文件和文件夾
