This error always occurs when installing mysql5.0 on XP. This error occurs because MySQL is installed on the computer and is not uninstalled. The specific uninstall method is as follows:
Control Panel-add and deleteProgram-Delete MySQL.
Delete C: // programe files/MySQL (MySQL is installed in c: \ Program Files \ mysql \ MySQL Server 5.0)
Delete c: \ Documents ents and Settings \ All Users \ Application Data \ mysql
If the second file cannot be found, it is hidden. You can search for it and delete it.
After deletion, restart the computer. Follow the steps!
PS: There is a TCP port in the installation process. The default value is 3306. If the default value is 3307 in the configuration, it must be that an old version on the computer occupies port 3306. You need to thoroughly uninstall it.
