Actually, my default browser is Internet Explorer, fully updated. Obviously, if I accessed the update through the Piriform console(is that the correct term?) I meant to say, if I use a browser, I prefer firefox, and you all know why. Internet Explorer remains default since so many applications expect it.
I am no expert, but why does this condition happen only with the cc216 update? Other downloads I have performed with other applications have never prompted this way.
May I suggest, naively, while I am looking for problems on this end, that someone much smarter than me see if there is any connection between the cc216 update code and Windows Updates, or Symantec updates or something like that, that may cause this error message?
