I installed an Odoo Windows version 15 or 16 on my computer, it's successful.

However, I cannot open the page using browser as http://localhost:8069

The service is confirmed up.

I reviewed the log and found there is a keyerror "One_of_my_DB".

There is a previous installation of Odoo 13 and the PostgreSQL is previous installed.

I guess something left before messed up the Odoo 15 service start up, 

Do you have any idea how I can esaily skip the previous config and start a new?

I don't want removing previous installed as everything have to be rebuilt.

Thanks.
