Netware 6.5 SP6
ZfD 7 SP1 IR1

I have a server running different ZfD 7 services,
i.e. imaging, wks import/removal, NAL, WOL etc.

Now I also want this server to run an Inventory Database.
But when I run the ZfD 7 SP1 IR1 Winsetup.exe, only the already installed components
are checked on the eligible server (but greyed out, and cannot be changed).
Further I cannot add any additional components during the installation.
All checkboxes for the Inventory components (Database, Server, Proxy Server)
are empty and totally greyed out.

What do I do to change or add ZfD 7 components in such a server?
