Description:
Hi,

I am re-installing mysql on a Windows 2008 R2 Standard SP1 64bit.

I completely deleted my previous MySQL installation folders. I used all the default installation settings except for changing to port to 3366 and adding an administrator password. Port 3366 already has a Windows firewall exception and I have used this port with success previously on this machine.

The error occurs on the Instance Configuration Wizard when executing the configuration. Prepare configuration, Write configuration file, and Start service pass. The installation fails on the "Apply security settings" step. Here is the error:

"The security settings could not be applied to the database because the connection has failed with the following error.

Error Nr. 1045
Access denied for user 'root'@'localhost' (using password: NO)

If a personal firewall is running on your machine, please make sure that you have opened the TCP port 3366 connections. Otherwise no client application can connect to the server. After you have opened the port please press [Retry] to apply the security settings.

If you are re-installing after you just uninstalled the MySQL server please note that the data directory was not removed automatically. Therefore the old password from your last installations is still needed to connect to the server. In this case please select skip now and re-run the Configuration Wizard from the start menu."

Maybe it is worth noting the "using password: NO" text. I definitely configured a password.

How to repeat:
For me, I simply run the installer with default settings and the errors occur.

Is it a fresh install or you had used some older 5.5.x version on this machine?

Yes, we had used an older 5.5.x version (I don't recall the number).  Yes, I did delete the old installation directory.

Please try version 5.5.27. Thanks.
