Not in a position to check at present; I just recall that in the not so distant past I needed to go back a version or two on IE only to find the latest versions were integrated with Windows and could not be uninstalled. I recall the solution was to go to the Control Panel and find the IE service and disable it. If you are not knowledgeable that you know where to look and experiment, then I think we'll need to await a post from someone who is au fait with the procedure.
