PostgreSQL 16.3 install fails on Windows with domain user if a local user exists with the same name

First detected on a production system when trying to update from 16.2 to 16.3.

 

The problem is however reproducable with a fresh installation of version 16.3 and occurs under the following condition:

- A local user exists e.g. MyServer\DomAdmin and has a user profile under C:\Users\DomAdmin

- A domain user exists e.g. MyDomain\DomAdmin and has a user profile under C:\Users\DomAdmin.MyDomain

Shortly after starting an installation of 16.3 under the domain user, the following error occurs:

Error copying file from packed archive C:/Users/DomAdmin.MYDOMAIN/Downloads/postgresql-16.3-2-windows-x64.exe to C:/Users/DomAdmin.MYDOMAIN/AppData/Local/Temp/postgresql_installer_da4fcce335/prerun_checks.vbs:Destination not writable

The destination directory C:/Users/DomAdmin.MYDOMAIN/AppData/Local/Temp/postgresql_installer_da4fcce335 exists in the correct directory but it is owned by the local user MyServer\DomAdmin instead of MyDomain\DomAdmin

Installing 16.3. with the local administrator works without a problem.

In our case, the setup is however part of another application which must run under a domain user.

Thank for your support
