intellij idea - Can't update Android Studio - no "Update and Restart" button

Question

My Android Studio (0.4.3 now) often displays a message that is ready to update, but the alert does not have an "Update and Restart" button:

I want to install this update but I don't know how I can do this. After I click the "Remind Me Later" button few times, the fourth button on the left is sometimes visible, allowing me to download and install the update. I haven't discovered any pattern when this button shows up and when it doesn't.

Why isn't it always visible?

This is bug https://code.google.com/p/android/issues/detail?id=56737. If you dismiss the dialog and check for updates again, you usually get the button you're looking for. I don't know why this happens.
