I don't know about XC5 but older IE versions (IE8 and below I believe) support was dropped in XC4 some time ago and it was announced.

Unfortunately for everyone in love with (or stuck with) IE this is a necessary move. You cannot have modern and up to date website if you want to support this browser and its nonsense. IE until recently is not a browser you can run HTML5/CSS3 on. The fault here is not on XC but MS. And it has been for decades.
