ImportError: No module named Crypto.Cipher

[GoogleCodeExporter]

What steps will reproduce the problem?
1. Downloading a .zip of the new 1.7.0 version and running localhost for the 
first time (on my Windows machine using GAE 1.9.8)

What is the expected output? What do you see instead?
Just testing out 1.7.0 from the Downloads page and it didn't all just magically 
work like previous versions have. I was hoping to visit localhost:8080 and see 
the PowerSearching example class in my browser.  Instead I just got errors in 
the logs about Crypto.Cipher:

  File "C:\...\coursebuilder\common\crypto.py", line 26, in <module>

    from Crypto.Cipher import AES

ImportError: No module named Crypto.Cipher

What version of the product are you using? On what operating system?
CourseBuilder version 1.7.0 from my Windows machine which has GAE 1.9.8 
installed (not the newest 1.9.12).  I'll try it on my Mac tomorrow and I'll try 
GAE 1.9.12.  Everything goes better from a Mac. :) Just wanted to share the 
heads up early on my unboxing issue.

Please provide any additional information below.

I expected a git clone to have library linking issues, but I thought the 
Download version had all the libraries included.  BTW for updates to my courses 
is the best way to just do a Download of the .zip and move content over or 
should I be using git.  I'm sufficiently comfortable with git, but I've used 
the Download version in the past to make the library installations (much) 
easier, but now that I see updating is important I'm wondering if that is still 
the recommended path. (sorry about this side question in a technical issue).  
Just curious on your two cents.

Thanks,

I have the same problem in Windows 7 and this work for me...

The problem is that you don´t have installed the Crypto package in your Python 
installation, so you need to install it.

There is one prebuilt python binaries for windows called PyCrypto, I get the 
installer here:  http://www.voidspace.org.uk/python/modules.shtml#pycrypto

It detects where is you Python installation is and creates all you need to run 
Crypto and all its dependencies like _AES.

Hope this info was helpful.
