The initial problem was Toad 11.6 will not start. The banner flashes briefly nothing else happens. This was when Toad 11.6 was reading the Old-Format Term License Key from Toad 9.7. I renamed the whole Toad for Oracle folder in the App Data location; now Toad 11.6 at least asks for a license key now, but I get the AV error above if I use the Old-Format Term License Key.
