ieversion = parseFloat(regExp.$1);
if (ieversion >= 7) {
var embed = document.createElement("object");
embed.setAttribute("type","application/x-informationCard");
return ("" + embed.issuerPolicy != "undefined" && embed.isInstalled);
}
if (ieversion < 0 && navigator.mimeTypes && navigator.mimeTypes.length) {
var handler = navigator.mimeTypes['application/x-informationCard'];
if (handler && handler.enabledPlugin)
return true;
if (document.addEventListener) {
var event = document.createEvent("Events");
event.initEvent("IdentitySelectorAvailable",true,true);
top.dispatchEvent(event);
if (top.IdentitySelectorAvailable == true) return true;
}
