PostgreSQL version: 8.2.6
Operating system:   Windows Vista
Description:        Unattended install fails
Details:

mkdir c:\postgres
msiexec /i postgresql-8.2-int.msi  /qr INTERNALLAUNCH=1 DOSERVICE=0
ADDLOCAL=server,psql,binfiles,jdbc,psqlodbc SUPERPASSWORD="sitt0"
BASEDIR="c:\postgres" /L* log.txt

I am not able to install PostgreSQL as a service. The user is not created.
XP is ok, Vista is not. This example fails as well, even when I am not
installing the service.

Please advise.
