Docker: Looks something went wrong in step Looking for vboxmanage.exe

The same thing happened to me. At this moment I am using Windows Home.

At least in my case, what happened was that the environment variables DOCKER_MACHINE and DOCKER_TOOLBOX_INSTALL_PATH were not created for the system.

I just had to add them and it worked.

Solved the problem by cleaning my .bashrc file. More specific, i removed the cd , which makes perfectly sense.

I'm Windows 8.1 user, I got the same problem when I installing the Docker Toolbox.

Because I have a previous version of VirtualBox installed, so I uncheck the VirtualBox install option in the Docker Toolbox installer.

After the install and I run Docker Quickstart terminal and get the same problem looks like something went wrong in step 'looking for vboxmanage.exe'.

Look at the file D:\Docker Toolbox\start.sh, there are some code fragment：

STEP="Looking for vboxmanage.exe"
if [ ! -z "$VBOX_MSI_INSTALL_PATH" ]; then
  VBOXMANAGE="${VBOX_MSI_INSTALL_PATH}VBoxManage.exe"
else
  VBOXMANAGE="${VBOX_INSTALL_PATH}VBoxManage.exe"
fi

The start.sh use $VBOX_MSI_INSTALL_PATH and ${VBOX_INSTALL_PATH} Environment Variables to locate the VBoxManage.exe.

And I find my system variables VBOX_MSI_INSTALL_PATH is

D:\VirtualBox

and then, I change it to

D:\VirtualBox\

It works fine!

Or maybe you miss the VBOX_MSI_INSTALL_PATH/VBOX_INSTALL_PATH Environment Variables.

This is my first answer on stackoverflow, I hope this will help you! Finally forgive my poor english ):

For me, the problem was that the DOCKER_TOOLBOX_INSTALLPATH was only set for the user used to escalate priviligies at installation. When I run Docker Quickstart as my regular user, the DOCKER_TOOLBOX_INSTALLPATH variable is empty, producing the error. Setting DOCKER_TOOLBOX_INSTALLPATH system wide solved the problem.
