Hi @steffen_KNIME , thanks for the update. It did not work with doing an in-place update of 5.1.0 to 5.1.1, however, doing a fresh installation of 5.1.1 works. :slight_smile: Looks all fine now, i.e. none of the mentioned error messages and all the nodes can be used. best regards, Jan

cannot install RDKit, vernalis, and other community nodes
