How do I install PyOpenSSL on Windows 7 64-bit?

To get Scrapy working on HTTPS, I need PyOpenSSL, but I can't seem to get this to work.

So, is there a 64-bit version available? I don't see one... I have installed the 32-bit version but...

I currently get this error back from Scrapy:

ERROR: Error downloading <https://SOME_PRIVATE_URL_HERE>:  
  [Failure instance: Traceback: <class 'scrapy.exceptions.NotSupported'>:
  HTTPS not supported: install pyopenssl library

Does anyone have a clue how to obtain or compile a 64-bit version? Or is that unneccesary?
