Hi William,

I tested the following code and web.config file in ASP.NET 4.0 AppPool, and received an exception:

.aspx

<%@ Register TagPrefix="telerik" Namespace="Telerik.Web.UI" Assembly="Telerik.Web.UI" %>

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

<html xmlns="http://www.w3.org/1999/xhtml">

<head runat="server">

<title></title>

</head>

<body>

<form id="form1" runat="server">

<asp:ScriptManager ID="ScriptManager1" runat="server">

</asp:ScriptManager>

<div>

<telerik:RadCaptcha ID="RadCaptcha1" runat="server" ValidationGroup="Group" ErrorMessage="Wrong Code"

ForeColor="Red">

</telerik:RadCaptcha>

<asp:Button ID="Button1" runat="server" Text="ValidateCOde" ValidationGroup="Group" />

</div>

</form>

</body>

</html>

web.config

<?xml version="1.0"?>

</configuration>

After commenting (removing) the Captcha httpHandler from the <httpHandlers> list everything worked out. Here is the modified web.config that works:

<?xml version="1.0"?>
