Another issue in Docker Quick Start Terminal

Now when I run Docker Quickstart I still get this error:

Either VirtualBox or Docker Machine are not installed. Please re-run the Toolbox Installer and try again.
Looks like something went wrong… Press any key to continue…

If I open up an admin shell and run. I get the error below. Sure enough the file: C:\Users\bob.docker\machine\machines\default\ca.pem is not there.

“\Program Files\Git\git-bash.exe”

I get a git-bash shell and when I run ./start.sh I get this error:
