To update rdkit to the September release, I recently did a

*conda install -f --channel https://conda.anaconda.org/rdkit
<https://conda.anaconda.org/rdkit> rdkit*

on my Windows box, and everything seemed to update fine.

However now, when I try from rdkit import Chem, I get the disturbing error
message below.

Is this a sign that my particular installation got borked somehow, and I
maybe I should reinstall everything again?  Or is this perchance a known
issue with the 2016.09 release?  If the latter, how do I roll back to the
old release using conda?  I tried a *conda install --channel
https://conda.anaconda.org/rdkit <https://conda.anaconda.org/rdkit>
rdkit=2016.03.4 *but that didn't seem to do it.

Thanks all for any help!

Curt
