    Hello

    Does RadCaptcha use Silverlight?  In IE 11 I get a Silverlight warning on my pages that have RadCaptcha on them, I also get it on the RadCaptcha demo page, image attached.  is there any way to avoid this warning?

    Also, I realize that updating silverlight might make it go away for me, but I don't want it to happen for end users at all as we don't use silverlight on our site.

    Hello John,

    RadCaptcha has by default its audio enabled. In order to play the audio, however, it initially looks for an available plug-in in the browser including the silverlight plug-in. You can try to disable the audio:
    <telerik:RadCaptcha ID="RadCaptcha1" runat="server" CaptchaImage-EnableCaptchaAudio="false" ></telerik:RadCaptcha>

    Hello John,

    You can try the workaround from the attached sample. Note, however, that the workaround uses the latest captcha script. That means if you later upgrade and there are any updates in the script file they will not be reflected and may exhibit some issues.
