Windows 32 bit "Could not load native RDKit library"

I've just installed the RDKit plugin to KNIME 2.9.4 (fresh install) on Windows 32 bit, and I am now getting the

"Could not load native RDKit library: ...knime_2.9.4\plugins\org.rdkit.knime.bin.win32.x86_2.4.0.201405211049\os\win32\x86\boost_system-vc100-mt-1_51.dll: Can't find dependent libraries"

error.

Is there something I need to do to fix, or is there a problem with the 32 bit build?

Thanks

Steve

Dear Steve,

I tried to reproduce your issue (on a Windows 64 bit system, but with a KNIME 32-bit version), but it worked for me. It seems that your Windows 32-bit Operating System has a file missing that is required by the boost DLL that the RDKit is using. To find out what file is missing please run a dependency walker on the file knime_2.9.4\plugins\org.rdkit.knime.bin.win32.x86_2.4.0.201405211049\os\win32\x86\boost_system-vc100-mt-1_51.dll ...

There is another thread that at its very end discusses a similiar issue which was solved by copying over a missing DLL to one of the KNIME folders: http://tech.knime.org/forum/rdkit/solved-rdkit-broken-after-update - Please have a look and let me know if it helped.

Kind regards,

Hi,

I'm also experiencing issues.  After reading info on the RDKit forums and trying the dll fix, I still get these messages:

Can anyone please advise?  I'm running KNIME 2.8.2 on Windows 7 with 64bit.
