As the title says when I'm trying to install the update I get the updater screen but it just gets stuck on "Initializing" and the progress bar never changes and stays empty and it just sits there like that. I'm currently running 4.1.5.0.
Have you tried uninstalling it then reinstalling rather than trying to update from within Express?
