Re: ERROR 1045 (28000): Access denied for user 'root'@'localhost' (using password: NO)

I'm having issues attempting to upgrade MySQL.

I had version 5.0.91 running with no issues on a Windows 7 machine. I decided to attempt to upgrade to 5.5.11.

I uninstalled 5.0.91, and deleted the Mysql folder located in C:\Program Files.

Installed 5.5.11 with no issues. Ran the configuration wizard. Specified a root password that is the same as the old version. When the configuration wizard attempts to apply my security setting I get a message stating ERROR 1045 (28000): Access denied for user 'root'@'localhost' (using password: NO)

I attempted to uninstall 5.5.11 and go back to 5.0.91 and now the 5.0.91 installer is giving me the same message.

This is driving me up the wall and I'm getting very close to wiping the machine and starting over, research into this online says it was a bug as far back as '08.

Any help is much appreciated
