Just had some weird issues with IE11 that I tried to fix by reinstalling. However, I could not find an entry to uninstall in Windows components nor in Programs and Features. I could also not install the latest version via installer because it reported that a newer version was already installed. Bump.
Fortunately, there are logs that can be used to trace what is going on.The Internet Explorer installation log is at C:\Windows\IE11_main.log. Once the installer starts, it creates a temporary folder in C:\Windows\Temp\IExxxx.tmp. This folder contains the installation files and things can be manually adjusted there.
