It is the Error Code 9C59 which prevents both IE 10 and IE 11 from installing. After reinstalling Win 7 and using clean, high speed broadband for updating the problem remains. Tomorrow I will look more into it.
Are you absolutely certain that this is a clean, fresh install of Windows 7? Or have you done any customizations, installed third-party "power tools" (ugh!) or even (shock, horror) used a pirated version of Windows?
I'm asking because this is something that normally does not happen. You install Windows, take it for a trip to Windows update, and everything comes down fine, including whatever new versions of IE Windows Update is offering. This all indicates that the most likely cause of your problem is something irregular on either your Windows install or your net connection.
