prova il seguente:

I just came across this problem in MySQL 5, to fix it:

(1) Uninstall (using Windows control panel).
(2) Remove the MySQL directory manually (or move it somewhere if it's got data files you want to keep).
(3) Install MySQL again.

I also made sure the MySQL service was stopped before (1) and also I removed the services entry from the registry using regedit and rebooted, but you may not have to do this .
