title: Android Emulator won't start from Android Studio on Windows 10
body: <p>Recently (after install Android Studio 2.3.x, I'm now at 2.3.1) the emulator won't start in Android Studio.  </p>
  
  <p>I <strong>can</strong> run the emulator from the command line if it is in the SDK\tools directory.</p>
  
  <p>If I run the emulator from a directory other than the SDK\tools directory I get an error like this:</p>
  
  <pre><code>[12236]:ERROR:./android/qt/qt_setup.cpp:28:Qt library not found at ..\emulator\lib64\qt\lib
  Could not launch '..\emulator/qemu/windows-x86_64/qemu-system-i386.exe': No such file or directory
  </code></pre>
  
  <p>The tools and platform-tools directories are in my path.  Android_home is set correctly.  First I tried re-installing the emulator from the SDK manager in Android (now that the standalone SDK manager is gone I can't do it there).  I manually downloaded the SDK and installed it overtop of the old SDK.  I then tried putting it in a new directory and changing the ANDROID_HOME and updating my paths and changed the setting in Android Studio (and all the local.properties files).  Next I completely uninstalled Android Studio and SDK, rebooted and reinstalled Android Studio.  Still having the same problem.  </p>
  
  <p>I've tried the suggestions here in the question here: <a href="https://stackoverflow.com/questions/42659272/emulator-on-android-studio-doesnt-start-after-sdk-tools-update-to-25-3-1">Emulator on Android Studio doesn&#39;t start after SDK tools update to 25.3.1</a> by copying various directories (first sym-links then copy directories as sym-links work differently on windows).</p>
  
  <p>I've tried all the suggestions here: <a href="https://issuetracker.google.com/issues/37137213" rel="nofollow noreferrer">https://issuetracker.google.com/issues/37137213</a> as well.</p>
  
  <p>I've re-installed HAXM, but I don't think it is an Emulator problem as it does work when I start it from a command prompt in the tools directory. </p>
  
  <p>Any suggestions? </p>
  
  <p>Details:<br>
  Windows 10 (Build 1703)<br>
  Android Studio 2.3.1</p>
