Sdk Manager won't launch in Android Studio

Question

If I choose Tools > Android > SDK Manager from the menu, or click the SDK Manager icon on the tool bar, nothing happens. What can I do

Answer 1

In my case, after a failed update 0.3 -> 0.59, I had clean-installed (unzipped) the wrong version (update only, which started just fine, but without SDKs), I had to reinstall the bundle version to even have SDK manager.
