Thanks Donald.  I am not sure why that old zlib1.dll is needed but I
will look into it.  You can join the discussion (test, comment, provide
feedback) through the ticket at:

If you find any more issues be sure to record them in that issue
tracker, thank you.

You can also contact me directly, if your organization needs a custom
build, or you would like to support the development of this great product.
