Hello I am using Postgres 9.3.3.1 on Windows (32-Bit Windows 7 Professional). I use the installer executable postgresql-9.3.3-1-windows.exe with the option "--optionfile <file>" The option file has the following content (the ${..} are replaced with correct values before execution): #mode=unattended datadir=${program.base}data prefix=${program.base} serverport=${postgres.port} superaccount=postgres superpassword=${postgres.passwd} unattendedmodeui=minimalWithDialogs servicename=${postgres.service.name} 1) If the "mode" property is enabled to mode=unattended, the installation works silent but the whole 'data' folder is missing after installation (the first error message will occur when the server-startup failes after installation). 2) If the "mode" property is disabled, the Installer interface appears. Everything is correctly set, I need only to press the <next> button. The Installation completes correctly. Why does my unattended installation as described in 1) fail, but 2) succeeds? Thank you in advance for the help Peter. -- View this message in context: http://postgresql.1045698.n5.nabble.com/Unattended-Installation-tp5798154.html Sent from the PostgreSQL - general mailing list archive at Nabble.com. -- Sent via pgsql-general mailing list (pgsql-general@xxxxxxxxxxxxxx) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-general
