Q:

Create Environment Python-3.5 Errors

I just installed Anaconda (that installs Python 3.6) within Windows 10...and it worked fine.   I then tried to create a Python 3.5 environment: 
% conda create -n py35 python=3.5 anaconda
But the process fails on verification.   I've tried twice...and the verification lists 702 errors as below... Here are the top three (I've substituted 'UserName' for my user name): 
CondaVerificationError: The package for pyqt located at C:\Users\
<UserName>\AppData\Local\Continuum\anaconda3\pkgs\pyqt-5.6.0-py35hd46907b_5
appears to be corrupted.  The path 'Lib/site-packages/PyQt5/Enginio.pyd'
specified in the package manifest cannot be found.

specified in the package manifest cannot be found.

specified in the package manifest cannot be found. 

This should be straightforward:  install an environment, within Windows 10... 
Yet it fails... is there a step I've missed?  path variable unset? 

A:

have same issue.  And helped with this link. 
conda clean --packages --tarballs
