OK, a different point of view then...
I already have NW '04, Linux, MaxDB. In order to install NW '04, Windows, MSSQL, thinking logically,
I'd need:
RDBMS - don't know what is native to NW '04, but I could use MSSQL 2005, provided with NW7.
Kernel - this one is available
Installation Master - this is what I'm really missing. Could the IM from NW7 be used to install 6.40?
Installation Export - I believe that this is cross platform and DB independent, so I might use the one I already have...
