I had some issues to run rdkit from Python console in PyCharm (4.5.5) on
Linux. After recent installation of PyCharm 2017.1.3 it started to work.
Maybe updating PyCharm will help on Win as well.

We're having trouble getting RDKit to work in a PyCharm project using an
Anaconda interpreter (Python 2.7), on Windows 8.1.
Has anyone had success with this and can guide us?
The trouble is we get an
ImportError: DLL load failed: The specified module could not be found.
when trying to import rdkit (or rdBase).
We have tried many variations of the following, but here is a basic recipe of
what does/doesn't work:
1. Make a new conda environment (called 'eg1'), install rdkit ('conda install
-c rdkit rdkit')
2. From a cmd.exe prompt, use this environment ('activate eg1') load python
('python') and import rdkit ('import rdkit') it works fine.
3. From PyCharm, create a Project Interpreter (pointing to
'C:\Anaconda2\envs\eg1\python.exe'), and use this to run a script or create a new Python
Console in which you 'import rdkit', leading to the "DLL load failed" message.
4. We have tried manually adding a bunch of things to the "Interpreter Paths"
in PyCharm, but without success (perhaps we just didn't add the right thing).

Update: just before I hit "send" on this request for help, we stumbled across
this posting of the same problem, and solution, from Christian Ribeaud:
https://intellij-support.jetbrains.com/hc/en-us/community/posts/115000244450-DLL-load-failed
It seems that if we open cmd.exe, activate the environment, and then launch
PyCharm exe from there, it works.
I'm sharing this here because it took us a while to find the other post, but also to ask:
is there a "better" way?
Cheers,
Richard
