Script 70: Permission denied with popupmenu.js

The drop down menu not showing on documentum using java 6u25 on ie11 giving script 70: permission denied on line 305 bolded below: 

// Sanity check - make sure we've got a reference to the popupWnd.
// in which case we'll try to set it up here.
if (group.popupWnd == null)
{
var targetFramePath = getAbsoluteFramePath(group.targetFrameName);
group.popupWnd = eval(targetFramePath);
}
var wnd = group.popupWnd;
while (wnd != null)
{

I searched for a solution and found "MS16-104: Security update for internet explorer" but the non-security kb3191336 could not be found on Microsoft catalogue to be downloaded

Please help.
