I'm interested in running Community 9.0 on Windows Server 2003 (I realize this is not ideal, but this is what I have to work with).

I have successfully run the windows installer, but when I open http://localhost:5432, I get an 'ERR_CONNECTION_REFUSED' message.

Looking in the openerp-server.log, I can see the following error:

OperationalError: could not connect to server: Connection refused (0x0000274D/10061)

Is the server running on host "localhost" (127.0.0.1) and accepting

TCP/IP connections on port 5432?

Any idea about what could be causing this? Could it be related to postgre? I don't see the postgre processes running on the machine. Is there anything that needs to be done to configure the database after installing Odoo, or is that handled during the installation?

Any help would be appreciated.
