  Yes, tar can't replace the cygwin dll, because tar relies on having the
cygwin dll loaded in order to run!  You have to extract it separately and use
a dos prompt to copy it across.  You obviously read the FAQ entry, because you
knew to use the "--exclude=usr/bin/cygwin1.dll" option; read the bit just
after that again.  I guess it's only implied rather than explicit, that you
could have installed the dll first and the rest later; maybe we could make it
clearer.

  Yes: we were only suggesting *temporarily* disabling them to identify if
they were the source of the problem.  A lot of anti-virus programs are
actually buggy and modify the operation of the system by inserting hooks left
right and center; if, as a result of that, something stops working, because
the hooks inserted by the AV aren't actually transparent to the application
that is being hooked, then it's the AV program's fault, not cygwin's.  It
should be reported as a bug to the AV software manufacturer.


    cheers,
