Conda Python environment missing DLL file on Windows

I created a new Conda environment on Windows: conda create --name recco networkx

I then activated it with source activate. So far so good. Running conda list verifies that I have installed:

decorator 4.0.4
msvc_runtime 1.0.1
networkx 1.10
python 3.5.1

Ok, let's run python --version to make sure that everything is as it should be:

error

What does that even mean? When I deactivate and run python --version everything runs as expected and I'm handed back Python 3.4.1.

This issue is because something is going wrong with the msvc_runtime package. That package should contain these DLLs. Can you please verify the contents of your environment's root folder? These DLLs should live both in there, and in (prefix)/Library/bin.

One possible cause might be the wrong version of msvc_runtime: it should say [vc14] somewhere in conda list output for Python 3.5.x, and [vc10] for 3.4.x

One other cause might be that PATH is wrong after activation, and you're not picking up the DLLs correctly. Are you using cmd.exe or powershell? We don't support powershell yet - only cmd.exe is known to work. If using cmd.exe, can you post the output of echo %PATH% please?
