This is probably the mistake.

It looks lie the binary you're trying to run is not a native Windows
executable format and / or not an x86 executable at all. How does the
"file" command classify that executable?

To what end? Were any failures reported during the download? The nature of
Internet protocols (not to mention file compression formats) makes
undetected errors extremely unlikely. Apart from premature termination of a
TCP connection (which would lead to an incomplete download which would
subsequently be detected by the tool that unpacked the archive), there's
little likelihood that the data is corrupt.

Perhaps three (3) re-installs of Cygwin are in order?

That should be a clue. Cygwin is not a Linux binary emulator. It's a POSIX
emulation layer with its own libraries, tools and interface libraries.
Where a capability (such as program launching, e.g.) is present in the
underlying OS (Windows), then it's used (though indirectly). Among other
things, that means Cygwin uses Windows executable file formats, not those
of any Unix or Linux system.
This is probably why your program won't execute. In particular, since the
program (probably) has execute permissions and fails when used in an
exec(2) call, it is then interpreted as a shell script. It probably isn't a
shell script...

Most likely your Cygwin environment is fine.

Yes, they have. Get or create (build) a Cygwin version of the tool chain
you want to use. Some programming may be required...
