This morning (Feb 24th) we had a large majority of our users reporting a "Unable to launch this application" error when trying to join a Collaborate room.
The issue that was causing this failure has been addressed. To join a session uses should:
- Close all browser windows
- Clear out Collaborate Cache (see How Do I Clear Blackboard Collaborate Cache? )
- Delete all Collaborate "Meeting" files from the downloads folder
- Try joining the session again
(Number 2 and 3 can be done by using the "Clear Cache" icon on your desktop. See How Do I Clear My Cache? )
