title: sdkmanager don't open: I get only [=========] 100% Computing updates
body: <p>I had the same problem than here:<a href="https://stackoverflow.com/questions/48401422/how-to-open-android-sdk-manager-from-terminal">How to open Android SDK manager from terminal?</a></p>
  <p>That question was marked as duplicated of this one: <a href="https://stackoverflow.com/questions/24372664/how-to-open-then-the-android-sdk-manager-through-the-terminal">How to open then the Android SDK Manager through the terminal?</a></p>
  <p>But, as you can see in the comments it's really not a duplicated one because the problem is different.</p>
  <p>Anyway, neither of the answers to either question solved the problem for me.</p>
  <p>I have downloaded Android SDK, Command line tools only for Windows 10. And when I run: <code>.\sdkmanager.bat</code>, I get this message: <code>[=======================================] 100% Computing updates...</code> but nothing happens.</p>
  <p>I have installed Java and everything seems to be ok.</p>
