  <p>I followed all the recommandation already proposed but I still have the issue.</p>
  
  <p>I had some issues when I tried to update my Android Stduio to version 3.1.
  Thus, I uninstalled everything, then delete the directories, and cleaned C:\Users\.android, .AndroidStudio, ..</p>
  
  <p>But I always have the same message at the end, indicating that SDK tools directory is missing.</p>

  <p>And if I enter SDK Components Setup, I have the following window. I cannot click in the Android SDK box (insidcating already installed ?), and at the end the same message than above.</p>

  <p>I already spent a full day on this issue and I cannot find the solution. I would really appreciate some help !
  I work on Windows 7 (64 bits version)</p>
