windows X 64 bits, can see the packages are installed from Installed Software

  Erlwood Knime Open Source Cheminformatics    3.3.0.v201701271222   org.erlwood.features.cheminformatics.base.feature.group    Erlwood

  Erlwood Knime Open Source Core    3.3.0.v201701271222    org.erlwood.features.core.base.feature.group    Erlwood

However, can NOT find the nodes from Node Repository under name erlwood.

Anyone knows reason or do I missed anything?

Thanks!

sometimes I have the same problem with knime version 3.5.1, the erlwood node are installed but not recognized. I don't know if there is some incompatibility with other nodes
