I had previously installed the 64-bit version of MySQL 5.1 server under
Windows Vista x64 and both the installation and configuration were
successful. Then for compatibility reasons with something on which I am
working I realized I needed to install the 32-bit version of MySQL 5.0
server. Since I did not see anything about installing both on the same
machine, I decided to uninstall the 64-bit version and then install the
32-bit version. The uninstall ran successfully.

When I installed MySQL 5.083 32-bit under Windows Vista x64 it installed
successfully. When I try to configure an instance of that version, all
steps work successfully until the "Apply Security Settings" step, which
fails. The failure message is:

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

Error Nr. 1045
Accessed denied for user 'root'@'localhost' [using password: YES]'

I have never changed the password from the previous 64-bit version I
installed and then uninstalled and the 32-bit version I installed.

Any ideas of solving this problem ?

Did you deleted the data dir (inside Program Files) after uninstall ?? i
think that is was not empty and when the new install tries to set up
finds it and get messy (maybe because the 32 and 64 bit issue).
