so, I remember troubles like this last time I installed mysql on win.
The thing is, you have to remove all previous instalations COMPLETELY !
Even if this, that you have now, got corrupted it goes the same as in previous statement.
Completely means, everything relevant from registry, data folder, program folder, user folder ,...
Windows built in uninstall will not do that.
Use some of uninstalers that are plenty outthere.
Reboot, repeat upper instructions, Reinstall.
Repeat upper instructions severel times, if not working first time, until you succeed.
Unfortunately I don't have bulletproof recipe to do all that.
