Having trouble installing IE 10 on a Windows 7 Home SP1 laptop. The automatic update for IE 10 kept failing so I download the update and ran it manually. It is stopping at the point that it needs addition updates, the problem is that all the prerequisite updates are installed. I have checked out KB2818833 and downloaded the required prerequisites: KB2729094,KB2731771,KB2533623,KB2670838,KB2786081. When I run each update manually they say they are already installed, but update KB2533623 says that it is not “applicable to the computer” even though I found article about the newer KB2533623 and downloaded it. I am pretty well stumped.
