Problem during unistall plugin RDKIT

Hi everybody.

I've a batch execution problem  of the GroupBy node in KNIME 3.1.
Below the error log:

As suggested, I've tried to uninstall RDKIT plugin from Installed Software Menu.

Perhaps, RDKIT  is always in and executable, in the nodes list. How can I uninstall it permanently as do not met yet the error log?!

Thanks a lot!

 

The RDKit Types Feature is used also from other KNIME features (e.g. Erlwood Nodes) and as long as you have installed one of these features it will not really be deinstalled, but just disappears from the list of installed software. Looking in the plugins tab the RDKit plugins are still showing up. Even the nodes are showing up in the nodes repository. 

To really uninstall it, you would have to uninstall also all plugins that have depend on RDKit. I cannot tell which ones, I know only of the Erlwood Nodes. Maybe you can find an Eclipse plugin (as KNIME is based on the Eclipse platform) that shows you all dependencies between the installed plugins. 

The RDKit error itself is interesting ... if the DLL files are physically not there, then you really should reinstall. But if they are all there, then you may miss some Windows system libraries that these files depend on. Normally, those libraries should be there (KNIME would not bring them in), but I remember cases where users had to install them manually. Using a dependency walker software on the DLLs that cannot be loading would reveal which system libraries are missing, and Google would tell you quickly where to get them from.

Hope this help to get you started.

Kind regards,

Manuel

Thanks Manuel, your suggestions are precious.

Hi,

Just wanted to follow up on this helpful thread to post what I had to do.

I have KNIME running on Windows Server 2012 R2.

  • The server only had Microsoft Visual C++ 2008 installed

Downloaded the 2010 version from this Microsoft site and installed on the server and all was well in the world.

--------------------------

Also used this x64 dependency walker (thanks Manuel!)

I cant add anything to the problem, but I can add that the Vernalis nodes also rely on the RDKit plugin.
