Installation on Windows fails unless cryptography is installed separately

When I install FakeNet-NG on Windows 7 by running python setup.py install in an elevated command prompt, installation fails with the following error:

Installed c:\users\username\appdata\local\temp\easy_install-feuwer\cryptography-2.0.3\.eggs\pycparser-2.18-py2.7.egg
no previously-included directories found matching 'docs\_build'
warning: no previously-included files matching '*' found under directory 'vectors'
_openssl.c
build\temp.win-amd64-2.7\Release\_openssl.c(434) : fatal error C1083: Cannot open include file: 'openssl/opensslv.h': No such file or directory
error: [Error 5] Access is denied: 'c:\\users\\username\\appdata\\local\\temp\\easy_install-feuwer\\cryptography-2.0.3\\.eggs\\cffi-1.10.0-py2.7-win-amd64.egg\\_cffi_backend.pyd'

A work-around is to induce the installation to succeed by first running pip install cryptography. After that, running python setup.py install terminates successfully and FakeNet-NG works when I invoke it by typing simply fakenet in an elevated command prompt.

This is on

• Windows 7 Professional SP1 amd64
• Python 2.7.12 (x86 or amd64)
• VC for Python 2.7 from https://aka.ms/vcpython27

Please reopen if encountered again.

Appears to work with the latest version of python and adding cryptography to dependencies before pyopenssl
