Change:

<ajaxtoolkit:toolkitscriptmanager id="ScriptManager1" runat="server" xmlns:ajaxtoolkit="#unknown" />

To:

<asp:scriptmanager id="ScriptManager1" runat="server" xmlns:asp="#unknown" />

Check how you register the assembly, must be like:

<![CDATA[<%@ Register assembly="AjaxControlToolkit" namespace="AjaxControlToolkit" tagprefix="cc1" %>]]>

The real fix is to install .net 3.5 sp1 and can be found here (Ajax Control Toolkit expects a .net 3.5 SP1 runtime environment):
