I cannot completely understand what you are saying, but here goes...
The exact error would be helpful. It sounds like you are saying you have an old install. So, you'd need to run something like
Code:
SET PASSWORD FOR 'some_user'@'some_host' = OLD_PASSWORD('newpwd');
or depending on the mysql version, you may be able to just delete an old my.ini file in your windows folder. You'll may need to rerun config setup.
