Can't run Docker Toolbox on Windows 7. ´Setting env´... Press any key to continue

Hi. I m new with Docker. Try to set up it on Windows 7 and get this error:
´Setting env´… Press any key to continue…

  1. I download Docker Toolbox from official site.

  2. Installed it.

  3. Installed virtualbox.exe from Docker directory.

  4. When i run QUICKSTART DOCKER TERMINAL, first there are some settings, linux os is created in virtual box, ssh,ip… and then i get it: “Looks like something went wrong in step ´Setting env´… Press any key to continue…” And then it closes.

Also i try to start start.sh by cmd, git, everything and get this error. VB is working all this time.
I reinstalled everything, changed iptions whi;e installing, but all the time i get this error.
I can see docker’s installed version, can run docker-machine and so on, but i can’t start this terminal.
I searched in google everything, there are too few errors like that.
What i m doing wrong?

My OS is Windows 7 Ultimate, version 6.1
Docker version 18.03.0-ce, build 0520e24302
Virtual Box 5.2.8 r121009 (Qt5.6.2)

How can i run my docker quickstart terminal on windows 7 and get message about sucess and then run hello-world?

Pls help to resolve dat
