Hi Eric,
as I mentioned, I do not have access to ChemDraw, so I am afraid I can't
help more with that.
A possible workaround is to install OpenBabel in your conda environment
and use that to do a cdx->mol conversion. While it should be possible to
use the openbabel or pybel module, for some reason I couldn't get it
work, so in the example below I am calling the obabel.exe executable.
import subprocess
from rdkit import Chem
from rdkit.Chem.Draw import rdMolDraw2D
from IPython.display import SVG
RDKit WARNING: [17:45:59] Enabling RDKit 2019.09.1 jupyter extensions
proc = subprocess.Popen("obabel.exe -i cdx 1oit_2d.cdx -o mol".split(),
stdout=subprocess.PIPE, stderr=subprocess.PIPE)
stdout, stderr = proc.communicate()
rdk_mol = Chem.MolFromMolBlock(stdout.decode("UTF-8"))
drawer = rdMolDraw2D.MolDraw2DSVG(400, 400)
Chem.Kekulize(rdk_mol)
rdMolDraw2D.PrepareAndDrawMolecule(drawer, rdk_mol)
drawer.FinishDrawing()
svg = drawer.GetDrawingText()
SVG(svg)
This should allow you to easily automate the SVG (or PNG) generation
process.
HTH, cheers

Hi Paolo, all,
Thank you for responding. I tried this out this morning - though I
could not find chemdraw using the combrowser.
Instead I went to the registry editor grabbed the CLSID from
HKEY_CLASSES_ROOT\ChemDraw.Application.15.0\CLSID. (As far as I
understand this should be identical to the GUID) I replaced the GUID
in
\Local\Continuum\anaconda3\pkgs\rdkit-2019.09.1-py37h422b363_0\Lib\site-packages\rdkit\utils\chemdraw.py
- however, I'm not seeing any change in the error when I go to import
via "from rdkit.utils import chemdraw".
Please let me know if I am doing something wrong.

Hi Eric,
it looks like the GUID in rdkit/utils/chemdraw.py might be outdated.
Unfortunately I don't have access to ChemDraw, so I can't test
this myself, but you might be able to find the current ChemDraw
GUID as follows.
From a Python prompt, issue the following commands:
|fromwin32com.client importcombrowse combrowse.main()|
This will pop up a COM browser. Expand the "Registered Type
Libraries" and look for ChemDraw.
Expand it, and you should find the IID (which is a GUID)
corresponding to ChemDraw.
Try replacing 5F646AAB-3B56-48D2-904C-A68D7989C251 in
rdkit/utils/chemdraw.py and see if it helps.
Cheers,

Hello all,
I'm trying to make use of the rdkit.utils.chemdraw to automate
conversion of cdx files to png's. and other formats. However, I'm
getting the following error message: ImportError: ChemDraw
version (at least version 7) not found.
I'm currently using windows 10 with anaconda 3 with rdkit
2019.09.1 installed from conda forge. I do have chemdraw
professional 15.0 installed, so I am wondering if there is
anything that I need to do to the path, etc.
