Smarteam R19-System configuration editor on Windows server 2008 64bit

With R19 – only Foundation (core services/vault setup) is supported on Windows 2008 (64 bit).
As System Configuration Editor is part of Editor installation, It cannot be installed on 2008 (64bit)server and will not show up during installation process. As a workaround, Install admin editor client on a supported operating system.

R20 supports 2008 (64 bit) and installing System config editor will not be an issue.
