If your computer has previously installed MySQL, if you do not delete it completely after uninstallation, there will be problems with the next installation. Here is a complete uninstall method for uninstalling MySQL 5.5:

1. Delete in the add and delete program in the control panel

2. Delete the my.ini file under the MySQL folder (under the installed folder). If the backup is good, you can delete all the folders directly.

3. Start-> run-> regedit to see if these places in the registry have been deleted.

Delete the HKEY_LOCAL_MACHINE\ SYSTEM\ ControlSet001\ Services\ Eventlog\ Application\ MySQL directory

Delete the HKEY_LOCAL_MACHINE\ SYSTEM\ ControlSet002\ Services\ Eventlog\ Application\ MySQL directory
