Why is ActiveX not generated in IE11?

Question

JavaScript

In IE11, the page executes the following code

// Get access to the server object
    var Server;
    try
    {
        Server = new ActiveXObject("ServerName.Server");
        Server.Connect();
    }
    catch (error)
    {
        Server = null;
    }

but there is an exception "It is impossible to create an object by the object programming server".
Third party ActiveX component. IE11 settings allow ActiveX, component is loaded, publisher not checked, 32-bit architecture.
Who blocks, how to calculate?
IE8 loads the component fine.
