Thanks for your help,
I have downloaded it this morning, I think that this is the last version.
I try to install CuteEditor on DNN 2.1.2 and DNN 3.0.13
DNN 3.0.13 I have copied file in BIN folder into DNN BIN folder, then I have copied CEHtmlEditorProvider folder into DNN/Provider/HtmlEditorProviders/. Now I have replaced original web.config with web.config of CuteEditor DotNetNuke_3.0 folder. In this case I cannot more enter on DNN. If I change web.config with older version all It's normal.
DNN 2.1.2 I have covered the same steps, but in this case I enter within DNN but when I try to edit HTML/TEXT Module as soon as created DNN does not visualize editor to work only a blank page.
