If I try to install Office 2010 with /adminfile switch via ZCM with
credentials from NSS (NetWare 6.58) volume
it will just throw the error:

the language of this installation is not supported by your system

If I just run the same command directly from same location (with a user
having admin rights on local workstation) there is not a problem

I really am losing my will to deal with ZCM **** behaviour
(I never managed to install Office 2007 in same way either)
