before I upgrade to Windows 10, it says I need to have IE 11 first.....ok, so I try to download IE 11.....it gets half way thru and says I need to have IE 11 prerequisites......the prerequisites are already installed on my computer but it's not seeing them....I'm in an endless cycle and can't get past the "prerequisite" message.....I'm stuck....I want Windows 10....what do I do?
