title: cant launch emulator on Android Studio - Unable to locate adb err
body: <p>Can't run any android app because it is unable to locate adb. When I click on &quot;launch this AVD in the emulator&quot;, I get an error message &quot;Unable to locate adb&quot;. I did look in the Android/Sdk/platform-tools, I have an &quot;adb&quot; executable. I tried to uninstall the folder and reinstall it - didn't help.
  I use Android Studio 4.1.1 on Windows.</p>
  <p>Thanks in advance.</p>
