I'm trying to reinstall SIM 7.6. I was able to uninstall the previous instance but it did not remove the old database (which I want it to do). When I try to run the install I get as far as the database selection and there doesn't seem to be a way to just start fresh with a new database. It detects the old one but I have no idea what the password is. I can't simply uninstall the SQL server beacause other programs are using it. All I want to do is start with a fresh database. How do I do that?
