He just means that you must provide matching Cygwin DLLs and exes which are
either all built as x86 (32 bit), or all as x86_64. Cygwin x86 programs will run
on Windows x64 or x86 desktops as they support x86 programs.

support, which MS has still not rewritten for x64.

More explanation would be helpful.
He could setup a package download structure, including setup-x86[_64].exe and
setup.ini, zip that for transfer, unzip that in a known location, then run the
included setup in unattended mode with fixed arguments, to setup the Cygwin
environment, install the base and other packages.
Have you other suggestions?

What problems do you see with his process?
