Okay, that all looks good, so far.

This is correct; you declined to install the GUI component of the
installer, so you can hardly reasonably expect to "continue" to a phase
in which it is then going to run it.  If you don't install the GUI, it
is assumed that you will use the command line "mingw-get" to complete
your installation.

Okay.  Once again, so far so good.

You might consider adding C:\MinGW\bin to your $PATH, so that you can
run this simply as

   gcc sample.c -o sample.exe

Hmm.  The clue is in the message box dialogue: you have a dependency on
libmingwex-0.dll, which appears not to be installed.

I don't think you are doing anything wrong, but you do seem to have a
strange anomaly in your installation.  From whence did you download your
mingw-get-setup.exe?  The copy on OSDN.net is the most recent.  What
version of GCC are you trying to install?  There isn't *supposed* to be
a dependency on libmingwex-0.dll, (and I can't find one in my GCC-6.3.0
build tree), but IIRC, there was a build with such a dependency, for a
very short period, but I thought I had fixed that long ago.  Please
ensure that you don't have any old package files lying around, in your
mingw-get download cache (usually C:\MinGW\var\cache\mingw-get\packages).

As a quick work-around, you may choose to install libmingwex-0.dll ... I
see it in the installation catalogue, from the OSDN.net host.  A more
public spirited option may be to identify the source of the dependency,
(Microsoft's Process Explorer, or Dependency Walker tools may help with
this), so we can fix it properly, once and for all.
