title: Can't start AVD Manager or SDK Manager from Visual Studio 2017
body: <p>I installed Visual Studio Professional with Xamarin, but <strong>without</strong> Android SDK and Android NDK. Then I downloaded SDK and NDK separately, unzipped them and set their location in Visual Studio Options. I am able to create and run Android Apps and everything works fine. Except I can't launch either SDK Manager or AVD Manager from Visual Studio. When I click corresponding buttons nothing happens. Android SDK folder doesn't contain exe files of AVD and SDK Managers. </p>
