How did you download Cygwin Setup: browser download from Cygwin home page, wget 
of link, or curl from link?

What are the permissions, size, path, and name of the downloaded file?
Try running `chmod -c a+rx .../setup-x86_64` to force executable permissions.

How are you running the program: using the full Windows or Cygwin path?
Try running `which setup-x86_64` to see which if any file is executed.

Why would you think that?
Programs that don't run either continue not to, or run when conditions are changed.

Cygwin enables permissions allowing execution under Cygwin and ignores settings 
which may prevent execution under Windows.
