Default installation path: C:\Program Files\mysql (not necessarily in the C drive to see which disk you are installing)

Database File storage directory:

Xp:c:\documents and Settings\All Users\Application Data\mysql

Win7/win8:c:\programdata\mysql (the directory is usually hidden and needs to be selected for display)

3, in the registry query MySQL, delete all (this step is critical, the main reason for the installation failure is the registry delete is not clean)

Here's how to completely delete the registry:

C. hkey_local_machine\system\currentcontrolset\services\eventlog\application\mysql
