I just did a fresh install of KNIME on my local Windows 10 machine, and then installed the four available RDKit software packages through the “Install New Software” wizard in KNIME. After restarting the KNIME program, I immediately receive the following error messages in my Console window:

Is anyone else having this issue? And/or does anyone know of a way to resolve it?
Some things I’ve tried:
Doing a fresh install, as done here. (I was having the same issue in my prior installation, but wanted to make sure I didn’t do something funny the first time through.)
I tried installing the VS2017 Redistributables as linked in the error message above; however, those are outdated and so I could not install them.
I tried using a dependency walker to see what I was missing for the “boost_iostreams-vc140-mt-x64-1_67.dl” library, and receive several error messages that don’t explicitly tell me what is missing:
Error: At least one required implicit or forwarded dependency was not found.
Error: At least one module has an unresolved import due to a missing export function in an implicitly dependent module.
Error: Modules with different CPU types were found.
Warning: At least one delay-load dependency module was not found.
I’m wondering if it might be an issue with the use of boost version 1.67, when version 1.70 is now available? Another odd–but possibly relevant–thing about the error messages about the boost library (the first set of errors I posted above) is that the first two messages are telling me that it can’t find the dependencies for the boost library at path, “C:\Program Files\KNIME\plugins\org.rdkit.knime.bin.win32.x86_64_3.7.0.v201905200540\os\win32\x86_64\boost_iostreams-vc140-mt-x64-1_67.dll.” And then the third message tells me that the file is missing altogether, even though it clearly is not since it gave me the path to it in the first two messages. Not sure if that message should be saying “cannot be loaded” as opposed to “missing,” but if not, then maybe this is related to my issue.
In any case, any help would be greatly appreciated!
Well, after many efforts of trying to figure out the library dependency issue (as well as trying this out on separate computers–both running Windows 10), I eventually found a way to get around my problem: Download KNIME version 3.6.2. (Originally, I was trying to use the latest version of KNIME 3.7.2.)
I suppose this issue may be beyond my control, as at least based on my installation attempts, it seems to be related to a compatibility gap between the newest versions of KNIME and the RDKit extension.
I encountered the same problem today when I opted to update KNIME (3.7) with a new version of the RDKit-related features.
Thank you for your investigations, I’ll try to follow your instructions and “downgrade” KNIME again to retain a working RDKit on my system.
when i start the program i obtain the following errors in the Console i never had before:

They all seems related to RDkit and Vernalis extensions.
I’ve tried to reinstall Knime and reinstall those extensions but I can see the errors again. I think it’s something not related to our local configuration but something that goes wrong with the plugins… hope they can fix it soon…
It is a problem introduced in the latest RDKit update. That also causes problems for some of the Vernalis nodes as they have a dependency on the RDKit plugins.
