thank you

Answer 1

Well , with Python & windows you'll find lots of similar issues. (I know 'cause i did)

One solution is to download OpenSSL in windows binary i believe it's located here http://slproweb.com/products/Win32OpenSSL.html

Of course You can also google "package name + windows binary" if this doesn't cut it.

Good luck.
