What does this mean

HI I was wondering if someone could please answer a simple question for me. I was wondering in the description of the lasted program update under the known issues it says

AOS plugin doesn´t work with “Enhanced Protected Mode” enabled in IE 11

What iI would like to now is what does that mean exactly. The reason I am asking this is because I have a Windows 7 computer with ie 11 currently on it and I just would like to now if I install this lasted program update on this computer that I can still use ie 11 without any issues at all.

Thanks very much for your time and your help always appreciated

This appears to be restricted to some windows 8.1 systems only. AOS crashes IE11

Thanks very much Exsexboy for your help

The setting in IE is Tools->Internet Options->Advanced->Security
