How do I detect if adobe digital edition is present on client machine or not ?

Question

Hello,
I am working on a project, whihc involves finding out if the client machine has adobe digital edition Ver. 1.5 installed.
I went through the Installer SDK, and the examples that come with it, especially ade_detect_layers.htm, however, I cant figure out the variable which will signify the presence of ADE.
By the looks of it, G_nADEInstalled variable should have it, but it always 0, no matter if the ADE is installed or not.
The ade_web_library.swf does reflect the state of ADE, i.e. if ADE is present, it displays - Launch, and if ADE is not present, is displays - INSTALL. However, I want the state information in a javascript variable.
Anybody got any ideas ?
-Thanks.

You should be able to detect ADE using the following mechanism.
Resources required:
swfobject.js
ADEBadgeLauncher.js
DigitalEditionsDetection.js
ade_web_library.swf
The 4 files above are provided by Adobe. It might be worth copying the
swf file in your web app, as I had some issues initially with using
adobe-hosted swf.
Apart from that, you need some new javascript functions:
Call the below function inline from the page, where you want to detect the ADE.
The second function below is the callback which is used by Adobe SWF.
I hope this makes things clear. It might be worth getting this working
on a local apache server before integrating with a web application.
And, check on both IE and firefox.
//Called inline from the page to detect ADE, and hide/show the layer
for installing the button..
function detectADE(swfPath) {
ADE_Detect_doOnLoad('', false, false, swfPath);
///doOnLoad(swfPath);
//This is a callback function invoked after the function
ADE_Detect_doOnLoad() has finished.
function setG_nADEInstalled(IS_INSTALLED) {
var obj = document.getElementById('ADE_ShowContentDiv');
if (IS_INSTALLED == '1') {
if (obj != null && typeof(obj.style)!= "undefined"){
//document.getElementById('ADE_ShowContentDiv').style.visibility = "hidden";
Thanks
