I can install Office 2007 Ent perfectly OK from NSS volume on NW server by
hand (user logged in, double click shortcut to a silen install with /admfile
O2007transform.msp )

Yet if I try to do the same with Bundle - Run as dynamic administrator with
network access credentials selected (that user has R rights to network
location) I get all sorts of errors like: "Osetup.DLL digital signature does
not validate or is not present" or even better BSOD on plain install of
Windows 7 SP1 x86 (not seen many of them for a while...)

If I do the silly way: upload to server, copy all to temp folder & then run
the setup it works

So obviously the network credentials bit is misbeahaving

ZCM 11.2.1 Update 2

Any ideas?
