I am trying to run RDKit on Windows 7, and I am getting the DLL load error
which, according to the documentation, is due to missing Microsoft Visual
C++ Redistributable files. It is a 64-bit system with 64-bit python 2.7,
and I have installed RDKit using conda as per the instructions. According
to my Control Panel I have the following MSVC packages installed:
Microsoft Visual C++ 2005 Redistributable 8.0.61001
Microsoft Visual C++ 2005 Redistributable 8.0.59193
Microsoft Visual C++ 2005 Redistributable (x64) 8.0.56336
Microsoft Visual C++ 2005 Redistributable (x64) 8.0.61000

Microsoft Visual C++ 2010 x86 Redistributable 10.0.40219

Here is the text from my conda install of RDKit:

What am I missing? Do I need to copy some of the MSVC files to a different
location? Do I need to set some environment variables? Thanks in advance
for any help you can provide.
