When I don't start Visual Studio as administrator, I get the following error:
Error Xamarin.Android for Visual Studio requires Android SDK. Please install it or set Android SDK path on Tools->Options->Xamarin->Android Settings menu.
In the options dialog, under Xamarin, the Android SDK Location is set to: "C:\Program Files (x86)\Android\android-sdk", which is correct, but there is a red X beside it, and not the green check mark.
Should the Android SDK be located elsewhere? Or is there some other problem at work here?
