Internet Explorer is already part of Windows 10 and you don't need to download it. Just to clarify, which operating system are you currently using? If you are using Windows 10 and you would like Google Chrome to be your default browser, go to Settings> Apps> Default apps> Web browser and choose Google Chrome. After that, kindly restart your computer.
