I cannot get the CA add-in to load properly in VS. I've tried installing both the latest release and beta release. When I activate the add-in I get the error:


The Add-in 'CAToolBar.connect' failed to load or caused an exception. Would you like to remove this Add-in?

Error Message: Class not registered

Error number: 80040154


Below is some information about my VS instance.
