RDkit and Erlwood nodes not working

Hi all,

I am new to using Knime and I have downloaded the latest version (4.1). I installed a few cheminformatic extensions including Erlwood and RDkit, but the nodes are not working properly. I get the following error messages:

WARN RDKit Descriptor Calculation 2:6 Could not load native RDKit library: no boost_serialization-vc140-mt-1_65_1 in java.library.path

ERROR Chemical Sketcher 2:8 Error while creating node dialog for ‘Chemical Sketcher’: null

I noticed that this was previously discussed in June/July last year, and that @greglandrum was very helpful with this.

Any help would be most appreciated.

Many thanks
