MySQL Server (5.6), Installer, Connector or WorkBench Wont't Install (Windows 7 64-bit)

If you’re having trouble installing MySQL on Windows 7 (Any other platform will probably be the same) then I’d recommend the following process.  Don’t skip the first steps that describe the uninstall and removal of the previous install as this seems to clear up most issues.   

Caution: deleting the data files will delete any data previously entered into MySQL.

1.  Remove previous MySQL installs (and remnants)

a.  Stop the MySQL service ( Start | Control Panel | System & Security | Administrative Tools | Services)

b.  Remove All programs with MySQL in the name from Windows Add or Remove Programs (Start | Control Panel | Uninstall a Program)

c.  Delete the MySQL data directory (It is a hidden folder) from  (You will lose any stored data so you may wish to make a copy) :
       c:\Users\{Your Username}\AppData\Local\MySQL

       c:\Users\{Your Username}\AppData\LocalLow\MySQL

       c:\Users\{Your Username}\AppData\Roaming\MySQL

d.  Delete the MySQL folders from

        c:\program files\MySQL\

        c:\program files(x86)\MySQL\

        c:\program data\MySQL\                --(this is also a hidden folder)

————–

That’s it for the removal and clean up.  Now, we’ll begin the install.

2.a  Go to the MySQL Website and install the latest MySQL Installer.  It should come in the form of an MSI installer and comes for a 32 bit machine(x86) but will run on a 64-bit machine.

b.  Launch the installer which can be found in your Downloads folder.  Follow the Wizard through to the end and make sure you make note of the password you set for your new installation of the server in case you forget it 

TROUBLESHOOTING

What if it didn’t work?

1.  Check the service from the control panel.  Is it running?  If so, try to log into MySQL.  I’ve seen instances where an error was received, but it completed successfully.  If it’s not running, try to start it and please post the complete error message.

2.  Check the error log.  It’s in C:\Users\AppData\MySQL\MySQL Server 5.6\data   It has an .err extension and you should be able to open it with notepad.  Ignore any errors about the innodb plugin not loading.  It’s a symptom, not the problem.  Look for an error about missing data files or a mismatch in file sizes.

3.  1045 error?  It should indicate Password: No or Password:yes.  If “yes”, it’s not a port issue, not a firewall issue — it’s a password issue.  It’s usually caused by not deleting out the data files from an old install.  The password is kept in the data directory and it’s likely that the password you entered during the previous install doesn’t match what you’re entering now.  You can either re-install after deleting all the files or try to reset your root password.  (resetting root password: http://dev.mysql.com/doc/refman/5.1/en/resetting-permissions.html )
