Silverlight version issue

Question

I'm using Silverlight v4 on my web site. If Silverlight is not installed, I degrade gracefully by showing a static image of my own choosing. However, I don't know how to do the same if the minimum runtime version of Silverlight is not installed. If the minimum SL run time is not met, I get the Microsoft SL image, which I don't want. Here's what I'm doing inside my object tag:

<param name="minRuntimeVersion" value="4.0.50401.0" />
<param name="autoUpgrade" value="false" />
<div class="down-level">
    <a href="http://www.microsoft.com/getsilverlight/get-started/install/default.aspx"&gt;
        <img src="images/occ.png" width="262" height="117" alt="For a more dyanmic experience, click to install Silverlight"/>
    </a>
</div>

Any suggestions would be greatly appreciated. Thanks.

In this case you will have to use silverlight.js to check for the version of silverlight installed and if it is below v4 show the user your custom message (show/hide your div). If version is 4 or up you will have to create silverlight object dynamically using silverlight.js again.
