javascript: "Object doesn't support this property or method" when ActiveX object called

I've got simple html on Login.aspx with an ActiveX object: 

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html>
<head><title></title>
<script language="javaScript" type="text/javascript"> 

    function getUserInfo() 
    {
        var userInfo = MyActiveX.GetInfo();
        form1.info.value = userInfo;
        form1.submit();
    }

</script>
</head>

<body onload="javascript:getUserInfo()">
<object id="MyActiveX" name="MyActiveX" codebase="MyActiveX.cab" classid="CLSID:C63E6630-047E-4C31-H457-425C8412JAI25"></object>
    <form name="form1" method="post" action="Login.aspx">
        <input type="hidden" id="info" name="info" value="" />
    </form>
</body>
</html>

The code works perfectly fine on my machine (edit: hosted and run), it does't work on the other: there is an error "Object doesn't support this property or method" in the first line of javascript function. The cab file is in the same folder as the page file. I don't know javascript at all and have no idea why is the problem occuring. Googling didn't help. Do you ave any idea?

Edit: on both machines IE was used and activex was enabled.

Edit2: I also added if (document.MyActiveX) at the beggining of the function and I still get error in the same line of code - I mean it looks like document.MyActiveX is true but calling the method still fails

IE8 manages access to the ActiveX on domain level.

To fix it:

  1. IE8, Tools -> Manage Add-ons
  2. In "Toolbars and Extensions" find your ActiveX
  3. Right click - More information
  4. Click - Allow on all sites
  5. Enjoy

Maybe the other machine has a virus scanner or similar which silently prevents ActiveX use?

I think the onload event is making the function to run even before the ActiveX object is loaded. You may try the following instead:

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html>
    <head>
        <title></title>
        <script language="javaScript" type="text/javascript">
            function getUserInfo(){
                if(document.MyActiveX){
                    var userInfo = MyActiveX.GetInfo();
                    form1.info.value = userInfo;
                    form1.submit();
                }
            }
        </script>
    </head>
    <body>
        <object id="MyActiveX" name="MyActiveX" codebase="MyActiveX.cab" classid="CLSID:C63E6630-047E-4C31-H457-425C8412JAI25"></object>
        <script for="window" event="onload" language="JavaScript">
            window.setTimeout("getUserInfo()", 500);
        </script>

        <form name="form1" method="post" action="Login.aspx">
            <input type="hidden" id="info" name="info" value="" />
        </form>
    </body>
</html>

Now the getUserInfo() function will start to run 500 milliseconds after the page is loaded. This must give some time for the ActiveX object to be loaded.

Maybe the ActiveX needs some prerequisite (For example CRuntime) that isn't present on the other machines? Have you tried running depends for the Activex on the hosting machine?
