How can I check with Javascript if the Lync Addon is installed in Internet Explorer?

Is there a solution to detect if the Lync-Addon is installed and active in my Internet Explorer using Javascript?

I know how to detect an Addon like Adobe Reader: 

try {
    new ActiveXObject("AcroPDF.PDF");
    alert("Adobe Reader is installed");
} catch (err) {
    alert("Adobe Reader is not installed - " + err);
}

But i dont know how i can detect the Lync-Addon. Is there an ActiveX-Object like the Adobe Reader one?

Thanks in advance and sorry for my bad english im not a native speaker.

The Lync plugin (Lync 2013) registers in Internet Explorer as follows:

Name:                   Lync Browser Helper
Publisher:              Microsoft Corporation
Type:                   Browser Helper Object
Architecture:           32-bit and 64-bit
Version:                15.0.4420.0
File date:              ‎01 ‎October ‎2012, ‏‎21:47
Date last accessed:     ‎12 ‎February ‎2013, ‏‎08:11
Class ID:               {31D09BA0-12F5-4CCE-BE8A-2923E76605DA}
Use count:              47
Block count:            0
File:                   OCHelper.dll
Folder:                 C:\Program Files\Microsoft Office\Office15

One of the objects exposed is the NameCtrl:

new ActiveXObject('Name.NameCtrl');

This should not error if the Lync client is installed.

As @Webritos mentions, the real ActiveX object seems to be new "OCHelper.BrowserHelper.1". However, when you try to instantiate that, you get the following error (at least in IE11 with Lync2013):

new ActiveXObject("OCHelper.BrowserHelper.1");
"Automation server can't create object"

new ActiveXObject("OCHelper.BrowserHelper.1");

Where 'OCHelper.BrowserHelper.1' is the ProgID of the Lync Browser Helper.

You can use this program to obtain information about ActiveX components installed on your computer http://www.nirsoft.net/utils/axhelper.html

About'Name.NameCtrl', I believe is not related to Lync (but it can be used for things like showing online user in a website) https://msdn.microsoft.com/en-us/library/office/ms455335%28v=office.14%29.aspx
