Get version of juce ActiveX Browser Plugin

Windows
1

How would I detect the version of my Juce ActiveX Browser Plugin via Javascript, without actually loading it?
The way to do it with for instance the shockwave plugin is:

var control = null;

try
{
    control = new ActiveXObject('SWCtl.SWCtl');
}
catch (e)
{
    return;
}
if (control)
{
    version = control.ShockwaveVersion('').split('r'); //this obviously doesn't work for a Juce Plugin...
    version = parseFloat(version[0]);
}

I can successfully initialize my plugin with new ActiveXObject(myProgID), but I don’t know how to get the version info from JuceBrowserPlugin_Version or JuceBrowserPlugin_WinVersion.

Any ideas? Thanks
