PostgreSQL install failing on Windows Server 2008 R2

[itsme]

Hello,

I first tried to install postgresql-11.1-1-windows-x64.exe on Windows Server 2012 R2 and everything went fine.

Then I tried to install postgresql-10.6-1-windows-x64.exe on Windows Server 2008 R2 ( I also tried postgresql Version 9.x / postgresql version 11 doesn't support Windows Server 2008 R2 anymore)

I always get the same error message during initialising the database cluster :

In the install-postgresql.log I found:

[15:46:07] Installing the adminpack module in the postgres database...
Executing C:\path\pgsql\bin\psql.exe -c "CREATE EXTENSION adminpack" -d postgres
Script exit code: 2

Script output:
 

Script stderr:
 psql: konnte nicht mit dem Server verbinden: Connection refused (0x0000274D/10061)
    Läuft der Server auf dem Host »localhost« (::1) und akzeptiert er
    TCP/IP-Verbindungen auf Port 5432?
konnte nicht mit dem Server verbinden: Connection refused (0x0000274D/10061)
    Läuft der Server auf dem Host »localhost« (127.0.0.1) und akzeptiert er

I don't understand why the installation always aborts at this point.

localhost is running on this server (within WAMP) so several other web applications are running on this server.

I even opened the TCP/IP port 5432 in the windows firewall.

Does anyone know why the installation doesn't work?

Thank you in advance.
