Why is Visual Studio crashing on me?

Benjamin Anderson

Visual Studio keeps crashing on me with the following message: ![alt text][1] [1]:
http://techoverflow.int.westgroup.com/upfiles/vs_sucks.jpg The full text is: Exception Type: System.InvalidCastException Exception Message: Unable to cast COM object of type 'CommunicatorAPI.MessengerClass' to interface type 'MessengerAPI.IMessenger2'.

This solution worked for me:

The Forms team found the workaround for this issue:
http://social.msdn.microsoft.com/Forums/en-US/tfsgeneral/thread/bcc9b1a9-2bd5-4076-8a72-6ab34ee6f261 In the WebEx Connect preferences, select the Integrations category and uncheck the box labeled "Display WebEx Connect status in Microsoft Office applications". Give it a try.
