Some of the studio pc's were pushed the Windows Updates which included IE 10 and now the add-in does not run. Has anyone seen this before?
I presume you are using Windows 7?
I will test that IE 10 upgrade on one of my Windows 7 machines and see what's happening.
In case of Windows 8 (the full one--don't know about the RT one) if a Connect Meeting is accessed in Metro's IE there is now a message that your Meeting will open in the Connect Add-in--and it does. I say 'now' because Windows 8 has started to support Flash for all sites even in Metro; before that you couldn't launch Connect Meetings in Metro's IE 10 because of lack of Flash support. Good move by Microsoft: Give the choice to the users.
