    Bugfix applied to our version of Mono. https://github.com/Unity-Technologies/mono/pull/1492
    The Ookii.Dialogs library requires some basic COM Interop calls to work properly. With a recent update to our version of Mono, COM calls were disabled on all platforms. This patch of Mono will re-enable basic COM calls for the Windows platform.
