I was trying to install MySql on a Windows Server 2003 R2 server and came across this error when configuring… (ignoring the fact that the service also wouldn’t start)
The error was: “Error Nr. 1045 Access denied for user ‘root’@’localhost’ (Using password: NO) (or password Yes)”
The only solution that worked was found here:
I didn’t have a firewall setup so that was not an issue. Adding the lines to the “my.ini” file and restarting the service, then clicking “Retry” worked.
