Error installing PostgreSQL 8.3 (password short, not complex)

Hello,
I have already read the response to this problem here:
https://www.postgresql.org/message-id/BAY123-F33A4637C55066E65749D2EA9F10%40phx.gbl<https://www.postgresql.org/message-id/BAY123-F33A4637C55066E65749D2EA9F10%40phx.gbl>
But, I have the same problem but I cannot change the Postgre password because it is installed by another software called LINCS II, which is a software from a dealer.
The same setup works on other computers, therefore is a problem of policy configuration. I have tried with the Local Policy but I have the same problem. I cannot change the domain policy but I think that could be the issue.
I would really appreciate your support with this. Maybe you can tell me how to avoid the require of a complex password during the installation of postgre.
Best regards,
Tomas
