A user called in, wanting help troubleshooting an installation of Internet Explorer 11 that repeatedly and persistently failed. The error code was the same, 0x9c47. The error code means that a Windows Update, KB2729094, could not be found on the computer. Because it is listed as a prerequisite for IE11, the installation failed. It did not matter one bit that the update was already installed. Luckily, resolving it is pretty straight-forward – here’s how:
- Follow this link: http://www.microsoft.com/en-gb/download/details.aspx?id=30521
- Download the update
- Run the install
Now, when I did this, I got an error message saying the program did not apply to the computer. I accepted that message, then ran the installation once more, and it immediately installed, no problem.
