So Creo M070 on Windows 8.1 is not supported at all? IE 11 is the oldest version that you can get with Windows 8.1, and IE 10 with Windows 8. Adam, when you referred to uninstalling IE 11 did you mean completely so there is no version of IE installed on the computer? We are going to have some kids with brand new computers over the past couple of months that are running 8.1....
Thanks for everyone's help!
