SW freezes on splash screen at AURA add-in

Since the latest hotfix, Solidworks no longer launches successfully.  The splash screen launches and runs through some things like registry, .NET something, then says launching Solidworks, followed by "Loading add-in:  AURA...", then hangs there until I kill the process in Task Manager.  I've tried rebooting and disabling all add-ins via the registry (since I can't disable via the application), but it still tries to load that add-in and freezes.

Any way around this issue?  Also, what is the AURA add-in?  I don't remember ever enabling any add-ins/
