Hey, thanks for responding back!
If you have a Windows Operating System, Internet Explorer comes pre-installed and typically cannot be forcibly uninstalled. Therefore, you should be able to find this program by simply opening the Start Menu, and typing "internet explorer' into the search field. Both the folder, as well as the program itself should appear. If you wish, once IE is open, you can then have it search for the latest updates in the window itself.
However, if you have tried all other steps in my previous post, and are still experiencing issues, then please do not hesitate to let us know by submitting a new Support Ticket!
