error while running install.sql in community auth

>>You mentioned that you have an existing users table; Where did that come from?
I have a table called users that my application uses and that I created.
>>because you've got other code that is part of the problem.
and that is why I brought up building a demo app. I think I will create a brand new clean CI install and try using that. I will create a new database with new tables with sql.ini.  What I don't get is why the db_tables didn't work?
