error 776 while updating a fresh, but prepared install

[wiebittewas]

just have followed the description within c't 23/2015, p.98ff to integrate most updates into the installation of win7pro-x64, but when calling wsusoffline-update afterwards to install other updates, I get an error on 7 of 9 packages:

no error: kb2912390 kb2965788

error 776: kb2984976 kb3020388 kb3035132 kb3035126 kb3069762 kb3075226 kb3078601

the error-msg on all failed packages is:

Fehler: 776

Der Client einer Komponente hat einen Vorgang angefordert, der in Bezug auf den
Status der Komponenteninstanz nicht gültig ist.

(sorry, german install, translated something like: the client of a component requested an action, which is invalid for the state of that component)

the update-tree (as well for the install-integration as the later update-try) has been downloaded with a fresh wsusoffline 10.2, all hashdeep-calls say "Audit passed"
the installation is absolute fresh, no programs/driver are added after installation

my questions:

does anyone had similar msgs?
can I simply ignore this at this point, or will later updates fail, too?

I'll try to contact the people of c't for this problem, too.

As you're using a german installation of Windows I assume, that it would be OK for you, if I answer in German. If you prefer English, it wouldn't be a problem for me to answer in English.

Bitte Folgendes versuchen:
1) System-Neustart
2) alle Dateien im Ordner C:\Windows\Logs\DISM löschen
3) wsusou erneut zur Installation verwenden
4) falls der Fehler nicht durch den Neustart behoben ist (passiert auf manchen Systemen), die Dateien im Ornder C:\Windows\Logs\DISM bei einem Datei-Hoster hochladen und den Link hier posten.

Viele Grüße
