scipy 0.17 broken or leading to error in Windows 32-bit, 64-bit

Please fix scipy 0.17, as it is now installed by default rather than scipy 0.16.

After building my binary which has the scipy dependency using conda build, and installing using conda create onto a fresh environment, I get the error:

Downgrading to scipy 0.16 makes everything run smoothly again, so I believe that there is a shared library that isn't properly built in the scipy 0.17 package for windows.

scipy 0.17 for linux and mac osx works fine. Please fix it for windows!

Is this only a problem when creating a new environment? Which version of Python do you use? Are you on 32 or 64-bit? What is the output from conda info? Thanks.

It appears to now be working on one of my windows 7 machines after uninstalling anaconda and reinstalling... I shall test on the other systems monday.

I am getting the same error after upgrading to scipy 0.17 as well - Python 3.5 under windows 10

I can confirm this same error on Python 2.7 64-bit on Windows 10.
