Use whatever Windows shortcuts are provided to launch cmd; try as user and as
admin to see if there are differences; or from a Cygwin shell run:

	$ cygstart `cygpath $COMSPEC` /k

as /k keeps the window around so you can see any (error) messages.


To run Cygwin 32 under Windows 64, you have to download and run setup-x86 to set
up the Cygwin 32 registry entries and base environment.

If you add .../cygwin32/bin to your user PATH (after .../cygwin64/bin if you
have that installed) you can then run Cygwin 32 exes from Cygwin 64 or Windows
64 shells.

As stated, this is not recommended, but a number of us probably ran that way for
years, as Cygwin 64 initially lacked a lot of packages available only on Cygwin
32. For a few years now, packages to be released must be built and made
available for both Cygwin 32 and 64 environments.
