I have configured urlrewrite . Html but  FCKedition can not be used.

IN web.config I add the following code:
      <handlers>
    <add name="HTML" path="*.html" verb="*" modules="IsapiModule" scriptProcessor="C:\Windows\Microsoft.NET\Framework\v4.0.30319\aspnet_isapi.dll" resourceType="Unspecified" preCondition="classicMode,runtimeVersionv4.0,bitness32" />
     <add name="Rewrite URL" path="*" verb="*" modules="IsapiModule" scriptProcessor="C:\Windows\Microsoft.NET\Framework\v4.0.30319\aspnet_isapi.dll" resourceType="Unspecified" requireAccess="None" preCondition="classicMode,runtimeVersionv4.0,bitness32" />
       <add name="ASP.NET" path="*.aspx" verb="*" modules="IsapiModule" scriptProcessor="C:\Windows\Microsoft.NET\Framework\v4.0.30319\aspnet_isapi.dll" resourceType="Unspecified" preCondition="classicMode,runtimeVersionv4.0,bitness32" />
..
    </handlers>

In administration when I add the product FCKedition error.I tried to change urlrewiteting .htm the FCK use.
