hi,

edit v7 server conf file in path_install_openerp\server\openerp-server.conf, change ports for options :

xmlrpcs_port = 8071

xmlrpc_port = 8069

netrpc_port = 8070

with by example for v7 :

xmlrpcs_port = 8771

xmlrpc_port = 8769

netrpc_port = 8770

Now change option pg_path with pg_path which is defined in v6 server conf file, should be something like :

pg_path = C:\Program Files (x86)\OpenERP 6.1-1\PostgreSQL\bin

stop and start windows service line "openerp server 7.0" in configuration panel\administration tools\services

connect to openerp with url localhost:8769

If you just want to see created database v6 only for v6 database list and database created v7 only for database v7 list, create new role postgresql with pgadminIII :

go to start/all programs/postgresql/pgadminIII.

In pgadmin double click on "postgresql for openerp", enter password openpgpwd and valid (you can check box save password if you want).

Now right click on connexion roles, click on add connexion role.

Now enter values for :

role name : new_role_name (what you want exept openpg and postgres)

password : new_role_name _password (what you want)

password 2 : new_role_name _password (the same than before)

check box : can create database (or superuser if you want all rights for this role)

And in server config file modify options with new role name and password created in options :

db_user = new_role_name

db_password = new_role_name_password

stop and start openerp server 7.0 service in :

configuration panel\administration tools\services\

Hope this will work and help.

Bye
