Problem with Cygwin (64bit)

I am facing the problem that I am not able to install any kind of 64bit unix tools within a nanoserver container. For example I tried Cygwin64, but when I was starting one of the unix commands (e.g. pwd or tr), nothing was happend. And there was no error output as well?
Within a windowservercore container the cygwin was working but only in combination with piping. There was still no stdout output.

How to overcome this?

FYI: I am using Docker Community Edition Version 17.09.0-ce-win33 (13620) and most recent nanoserver and windowsservercore containers.

Thx in advance for help!
