title: Error in Docker: bad address to executables
body: <p>I'm trying to something with Docker.</p>
  
  <p>Steps I'm doing:
  - Launch Docker Quickstart Terminal
  - run docker run hello-world</p>
  
  <p>Then I get error like:
  bash: /c/Program Files/Docker Toolbox/docker: Bad address</p>
  
  <p>I have to say that I was able to run hello-world image, but now I'm not. I don't know what happend. </p>
  
  <p>I don't know if it matters however I had some problems at instalation step.
  Since I have git installed in non standard location. However it seems git bash.exe working correctly for Docker.</p>
  
  <p>My environment:</p>
  
  <ul>
  <li>Windows 10</li>
  <li>Git 2.5.0 (installed before Docker)</li>
  <li>Docker Toolbox 1.9.1a</li>
  </ul>
