I have tried installing docker on windows 7 (using boot2docker). However the console just exists abruptly and I am unable to see the error, much less run any commands.
In the installation I have tried both installing and not installing the VirtualBox. I have also tried un-installing and re-installing both docker and virtualbox. Nothing seems to work.
Here are the console errors I see when I run boot2docker -v up:
Boot2Docker-cli version: v1.3.0
