After installation of the Docker Toolbox 1.8.0a, I try to open Kitematic (Alpha) by Windows 8.1 environment. The setup process got halt at 99% and for awhile throw the error message as following
ENOENT: no such file or directory
With some key file “ca.pem” not exists. I got the way to resolve this issue by delete following directory,
and then try to open the Kitemetic again, now I’m be able to sign-in to Docker Hub.
