Internet Explorer 11 is Microsoft’s latest internet browser. You don’t necessarily need to install it, but if you don’t you will find that many features on certain websites are unavailable to you. If you don’t know how to find what version of Internet Explorer you are using, click Help > About Internet Explorer.
Many people have experienced the frustration of trying to install Internet Explorer 11. They think they have installed it successfully, because they have run the download and no errors have been displayed, yet when they run internet explorer, it is the old version that opens. So they download and run the IE11 installer again (and then maybe a third time) with no success.
Installing the old version of Internet explorer does not work! So don’t waste your time on that trick. If you fail to install IE11 the first time, save yourself the time, effort and heartache and assume that you don’t have the prerequisite updates for Internet Explorer 11.
Visit that page and work down the list to make sure that you have all the prerequisite updates. When you previously ran the IE11 download, it should have ensured that these updates were installed, but it can fail and not tell you so. In this case, plan B is to install these updates manually.
