WSL DS doesn't work on Windows 10 build 1709

[firelizzard18]

I don't think WSL DS works with the fall creators update (build 1709). This presents similarly to #30, but I think it's a different issue.

I believe this because one of the recent updates (build 1703 or 1709, I'm not sure which), changed a number of things about how the system works. For one, the windows store has multiple available distributions.

Using Anaconda Python 3.6:

$ python install.py centos:latest
[*] Probing the Linux subsystem...
[!] The Linux subsystem is not installed. Please go through the standard installation procedure first.

Attempting a fix from #30:

Warning: lxrun.exe is only used to configure the legacy Windows Subsystem for Linux distribution.
Distributions can be installed by visiting the Windows Store:
https://aka.ms/wslstore

Error: 0x80070002

To be clear, WSL is installed, and the Ubuntu distro for WSL is installed and not running. And I was running from CMD.
