I was not able to install Windows Live Writer 2008 on my server workstation, it would give the error:
Sorry, Windows Live programs cannot be installed on Windows Server, Windows XP Professional x64 Edition, or Windows operating systems earlier than Windows XP Service Pack 2.
BUT you CAN install the Technical Preview version on Windows Server 2008 !!!
Need a good book on Windows Server 2008, see Windows Server 2008 Unleashed
