MySQL is not installed, and precautions

Program: MYSQL 6.0 64 bit

Operating system: WIN2008 64-bit

The first installation always fails, WIN7 or WIN2008 are the same.

The first is about deleting MySQL:

Stop the MySQL service in the service (start-up---control panel--services--service). Open Control Panel-Add Remove Programs, find MySQL, uninstall. Or you can use 360 security guards to uninstall. You can also use the MySQL installation program to remove

Uninstall the installed MySQL, but this is only half for uninstalling MySQL, and another important half is to clean up the registry. We're going to enter the registry at the start-run inside input Regedt, open the registry

Find the item about MySQL to remove them all, to find an item for an item to remove them all, so that it will be available at the time of installation. In fact, the registry MySQL entries are these three items:

Hkey_local_machine/system/controlset001/services/eventlog/application/mysql

Hkey_local_machine/system/controlset002/services/eventlog/application/mysql

Hkey_local_machine/system/currentcontrolset/services/eventlog/application/mysql

About the registry whether on the WIN7 or on the WIN2008 are found in the above three places, delete can

There is also c:/windows under the My.ini file also deleted! ( in fact, there are many files to delete, in My computer all the hard disk search "MYSQL", all deleted )

This way, after removing the above four items, MySQL basically unloaded completely. If you are not at ease, you can find MySQL in the C drive and delete the related items.

Be sure to restart the installation before you remove it

Next is the question about installing to the last step, no response:

Install first, do not configure.

(Note is someone else's)

Then locate the "MySQLInstanceConfig.exe" program under the Bin folder in the MySQL installation directory

Go down all the way next.
