Did you put all that line in the install options? On the first page of the distribution package you define which MSI to use, the LANDesk.msi file in the install options you specify just that, the options, so:
/qb CORESERVER=ldcore SILENT_INSTALL=1 LDINSTALLTYPE=2 LDLANG=ENU CONSOLE_ONLY=1
/qb is only used when using the Windows Installer option, if you dont check that option, also remove the /qb
That was it.
Took the documentation to literally.
Thanks for your help Frank.
