I went one step forward by adding the lines below to the web.config file when I added cuteeditor.dll to the GAC. CE shows in the web page but the buttons do not show up properly and they do not work.

    <assemblies>
   
    <add assembly="CuteEditor, Version=5.0.0.0, Culture=neutral, PublicKeyToken=3858aa6802b1223a"/>
    </assemblies>
