Dear Peter,
I have just tried to install the wheel file that you mentioned (I guess
downloaded from http://www.lfd.uci.edu/~gohlke/pythonlibs/#numpy) and I
get the following (unexpected) error message on a Windows 10 64-bit OS,
even though I am running a Python 2.7 32-bit pip:
C:\Users\paolo>C:\Python27_32\Scripts\pip install
C:\Users\paolo\Downloads\numpy-1.11.0+mkl-cp27-cp27m-win32.whl
numpy-1.11.0+mkl-cp27-cp27m-win32.whl is not a supported wheel on this
platform.
Installing numpy from the standard pip repository works just fine:
C:\Python27_32\Scripts\pip install numpy
Collecting numpy
Installing collected packages: numpy
Successfully installed numpy-1.11.0
I would also make sure that there isn't a python27.dll somewhere along
your PATH locations; when I ran this script on my system
@echo off
for %%A in ("%path:;=";"%") do (
dir %%~A\python*.dll 2> NUL
)
it found C:\WINDOWS\system32\Python27.dll that I didn't know to be there.
Hope that helps,
Paolo

Hi Paolo,
Thanks for the reply. I did have a 64-bit Python installation but it
**should** have all been uninstalled.
I have the same as you when I run python and there is nothing in the
PATH which would suggest I’m picking up something from elsewhere.
Python 2.7.11 (v2.7.11:6d1b6a68f775, Dec 5 2015, 20:32:19) [MSC

Prior to installation of the RDKit files, I have also had to install
numpy (numpy-1.11.0+mkl-cp27-cp27m-win32.whl), scipy
(scipy-0.17.0-cp27-none-win32.whl), pip version 8 and scikit-learn as
I wanted to use the Random Forest classifier out of sklearn.ensemble
and had to have an up-to-date version of scipy to get that to do more
than a very small data matrix. To get that (scipy) to work I had to
have the numpy+mkl installation from the wheel file above or else I
find a similar DLL load failure for part of the scipy modules. All
these were installed by means of pip and should be Python 2.7 and
32bit versions.
Hence there are plenty of things that could be getting in the way of
the RDKit installation but I wondered if there was anything known
regarding this DLL error. Would redoing the installations in a
different order (ie RDKit before numpy & scipy) make a difference..?
Regards

Dear Peter,
I am running Windows 10 with 64-bit Python but I just installed 32-bit
Python 2.7.11 under C:\Python27_32 to test this out.
I unzipped RDKit_2015_03_1.win32.py27.zip into C:\, then opened up a
shell and issued the following commands:
Microsoft Windows [Version 10.0.10586]
(c) 2015 Microsoft Corporation. All rights reserved.
C:\Users\paolo>set RDBASE=C:RDKit_2014_03_1
C:\Users\paolo>set PYTHONPATH=%RDBASE%
C:\Users\paolo>set PATH=%RDBASE%\lib;%PATH%
C:\Users\paolo>C:\Python27_32\python.exe
Python 2.7.11 (v2.7.11:6d1b6a68f775, Dec 5 2015, 20:32:19) [MSC
v.1500 32 bit (Intel)] on win32

>>> import rdkit
>>> from rdkit import Chem

Could it be that you have a 64-bit Python in your PATH which gets in
the way? I get the error message that you got when try to import rdkit
and then Chem from a 64-bit Python shell.
Kind regards,
Paolo

Dear All,
I’m trying to install and run the latest RDKit version (2015_03_1)
for Python 2.7 and 32bit windows OS running Win10 from SourceForge.
I’m running into the “ImportError: DLL load failed: %1 is not a
valid Win32 application” and the links on the
RDKit/docs/install.html for Win7 are not helpful.
Any recommendations as to how I can get around this..? Usually
this is a conflict of versions 64/32bit but I have installed 32bit
versions of everything required.
Thanks in advance.
Regards
