Fixed a problem where MySQL could not be re-installed after uninstall, stuck in the last step

MySQL service problems are often the most troublesome, often need to reload, and re-install many people unload dirty residual files, more can not be installed. You will encounter this problem in the next. Reload MySQL to the last step when you're stuck on the second line of the last step

The solution is to delete the registry + DELETE data file after uninstalling

1 uninstalling MySQL

Uninstall the best use of the installation package with uninstall program Uninstall, or may not be able to unload clean, will be more troublesome

2 Deleting the installer file 3 deleting the Registry

Directories that need to be removed from the registry: cmd-and regedit
1.hkey_local_machine\system\controlset001\services\eventlog\application\mysql Directory
2.hkey_local_machine\system\controlset002\services\eventlog\application\mysql Directory
3.hkey_local_machine\system\currentcontrolset\services\eventlog\application\mysql Directory
4.hkey_local_machine\system\currentcontrol001t\services\mysql Directory
5.hkey_local_machine\system\currentcontrol002\services\mysql Directory
6.hkey_local_machine\system\currentcontrolset\services\mysql Directory

Such as:

4 Deleting a data file (important)
deleting C:\Documents and Settings\All Users\Application Data\mysql directories often application The Data folder is hidden and needs to be checked to show hidden folders. 5. Restart (must restart the computer to be effective)

After that, your MySQL reload will be fine!

SO happy!!!!
