I installed a newer version of MySQL, 3.23.32, over 3.22.32 without uninstalling it at first. So now I am having some problems and I wish to remove both of them so that I can re-install 3.23.32 without having any trouble using it. Maybe I know how can I do so? For your information as you might want to know, I installed both of them manually using .tar.gz . And I am using a RaQ 3.
