IE 11 won't install and IE 10 won't uninstall (Error 9C47)

    Question

  • I use a Toshiba Satellite laptop and Windows 7.

    I'm sure many others have had the problem of Windows Update refusing to let Internet Explorer 11 install (Error 9C47). I have tried troubleshooting. In the updates section, the "important update" is IE 11, but one of the "optional updates" is IE 10. However, I already have IE 10 installed on my computer, shown in my Installed Updates.

    I tried uninstalling the IE 10 shown in my Installed Updates but it will not uninstall, saying it "cannot be completed." This is the same message that comes up after trying to install IE 11.

    I have also tried installing IE 11 directly from the site, which comes up with the same error. I tried to install IE 10 from the site as well, but the error message said I already have an updated version installed.

    Please help, this is driving me insane.
