Question concerning failed installation of Postgres 8.2.3 on Windows XP

Dear mailing list,

I have got a problem installing Postgres 8.2.3 on Windows XP Pro having
all the latest updates.
All postgres installations, folders and the serviceaccount have been
removed before so that it was clean installation.

The following steps lead to a reproducible result on a few machines but
not on all:

I chose English as installer language and deselected all database
drivers (JDBC, NPSQL, ...) for installation.
Then I just clicked "Next" in the following installer pages leaving all
options as is. I entered passwords for both the superuser and the
serviceaccount.
I selected German (Germany) as locale and UTF8 as encoding.

Near the end of the installation a message box appears reporting the
following error:
"Failed to connect to the database. Procedural languages files are
installed, but are not activated in any databases."

These are the critical lines written by msiexec in its log file when
encountering the error:
