I tried searching and couldn't find this for 5.7, only 5.6.

I installed c5 and borked it all up, want to just erase the db and start again from scratch.

I deleted all the tables from the database and deleted /application/config/app.php and database.php but the site will not trigger the reinstall routine.

Do I really need to delete it all and reinstall, or is there a different file(s) that I need to delete the trigger the setup routine?

Thanks.
