Window 7, upgrade docker to toolbox

Hello,
I have upgraded docker to toolbox on windows 7. When I start Docker Quickstart Terminal i got error:

Welcome to Git (version 1.9.0-preview20140217)
Run ‘git help git’ to display the help index.
Run 'git help ’ to display help for specific commands.
BŁĄD: System nie znalazł w rejestrze określonego klucza albo wartości. (Translation from Polish: Error: system didn’t find value or key in register)
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…

What should I do to fix it?

Best Regards
sw

take a look on the CONSOLE of virtual box and run “sudo docker version”
