How to complete uninstallation of My SQL before a fresh install

I want to do a fresh installation of MySQL. An old installation make it’s impossible. The problem is that the new installation asks for the current password witch I don’t know before I can set a new root password. How to do?

I doubt MySQL would use the registry for that. It's storage should be more portable than that. (It's the same across all platforms.)

If this is a Vista or Win7 setup, try checking the "C:\ProgramData\" directory. If I remember correctly, this is where MySQL 5.1 stores it's data files.
Also check the users "AppData" directories. There may be some configuration files stored there.

Hey.

We need more details on your server.
What OS are you using?
Which version of MySQL?
What type of installation is it? (From source, M$ installer, Linux distro-package, etc..)

If you are using Windows, the chathura is right. You just need to completely remove the folders created by the old installation.

If its linux try with package name with rpm command, it will completely uninstall the mysql related installation,

The installation is on a Windows computer, the chathura86 way should work but doesn’t. All the old folders have been removed after the un-installation. Still the new installation of MySQL 5.1.45 ask for the current password as if an old installation is present. Could it be something in the registry? I think the old MySQL installation was 5.1.32.
