Silverlight page loads insecure content from Microsoft

Got it fixed! I downloaded the image and included it with our website changing this line:

<img src="https://go.microsoft.com/fwlink/?LinkId=161376" alt="Get Microsoft Silverlight" style="border-style:none"/>

to this:

<img src="SLMedallion_ENU.png" alt="Get Microsoft Silverlight" style="border-style:none"/>

Apparently this link "https://go.microsoft.com/fwlink/?LinkId=161376" will still re-direct to a HTTP path to get the image. So downloading the image and including it directly fixed it.

In the page that is hosting your XAP file you will find the anchor tag with the URL to download the Silverlight runtime. You can either remove it or host a download on your own site under HTTPS.

<div id="silverlightControlHost">    <object data="data:application/x-silverlight-2," type="application/x-silverlight-2" width="100%" height="100%">      <param name="source" value="ClientBin/xxx.xap"/>      <param name="onError" value="onSilverlightError" />      <param name="background" value="white" />      <param name="minRuntimeVersion" value="4.0.50826.0" />      <param name="autoUpgrade" value="true" />      <param name="windowless" value="true" />      <param name="AllowHtmlPopupWindow" value="true" />      <param name="EnableHtmlAccess" value="true" />      <a href="http://go.microsoft.com/fwlink/?LinkID=149156&v=4.0.50826.0" style="text-decoration:none">              <img src="http://go.microsoft.com/fwlink/?LinkId=161376" alt="Get Microsoft Silverlight" style="border-style:none"/>      </a>        </object><iframe id="_sl_historyFrame" style="visibility:hidden;height:0px;width:0px;border:0px"></iframe>    </div>

You can customize that whole anchor tag to pull content from your site.

You could change the HTTP to HTTPS links in the anchor file and that should solve the problem at hand.

<div id="silverlightControlHost"><object data="data:application/x-silverlight-2," type="application/x-silverlight-2" width="100%" height="100%">  <param name="source" value="ClientBin/xxx.xap"/>  <param name="onError" value="onSilverlightError" />  <param name="background" value="white" />  <param name="minRuntimeVersion" value="4.0.50826.0" />  <param name="autoUpgrade" value="true" />  <param name="windowless" value="true" />  <param name="AllowHtmlPopupWindow" value="true" />  <param name="EnableHtmlAccess" value="true" />  <a href="https://go.microsoft.com/fwlink/?LinkID=149156&v=4.0.50826.0" style="text-decoration:none">          <img src="https://go.microsoft.com/fwlink/?LinkId=161376" alt="Get Microsoft Silverlight" style="border-style:none"/>  </a>    </object><iframe id="_sl_historyFrame" style="visibility:hidden;height:0px;width:0px;border:0px"></iframe></div>
