I got a similar message when trying to install Cygwin from scratch. I
think the missing dll was cyggcc_s-1.dll (sorry, I did not take good
notes). I had to copy that file from a .tar.gz to /bin by hand, then the
install went thru.

Apparently there is a missing dependency.

Note: if you run an executable from Windows Explorer, you get a better
message about what DLL is missing (MS finally did something right!).

That makes it sound like a path problem.
