I'm having about the same issue. I'm bumping your topic so we can get some help. I'm migrating a site that uses CuteEditor heavily and having a ton of issues with the editor.

Yes. You can add an an entry to your Web.config file.   Example:  <add key=''CuteEditorLicense'' value=''c:/keys/CuteEditor.lic'' /> Hop it helps. If not, please let me know. 

I've got this error few times too.   I was wondering if a fix is available. I just recently bought the latest version of CuteEditor.   I'm attaching a screenshot for your consideration.    

Although a slightly different issue, this problem seems it may also be due to using the editor in nested UC's.

Hi njashq, For the DNN site host/admin, you should change this file ''Providers\HtmlEditorProviders\CEHtmlEditorProvider\CuteSoft_Client\CuteEditor\Configuration\Security\Admin.config'' Not the default.config Regards, Ken 

chalked: The current version is: CuteEditor 6.0 Build 2007-08-14   Please download version 6.5 then try again.   http://cutesoft.net/Downloads/   Keep me posted

I have downloaded it ... but still get the same error ...   Error 1 The page must have a <%@ webhandler class=''MyNamespace.MyClass'' ... %> directive. CuteSoft_Client/CuteEditor/Dialogs/_vti_cnf/ThumbJpeg.ashx

This always happens to me as well; I have to usually rip out any custom table styles as CuteEditor seems to not have any custom CSS classes for its table layouts. Has this changed?

Guys,   We put everything together and create an online demo:   How to use CuteEditor as an image selector?( Demo1 |  Demo2 ) This example demonstrates how to use CuteEditor as an image selector

Have you run the example files coming with the download package successfully?If you upgrade from the earlier version of CE, please make sure that you update the CuteEditor.Dll and all CuteEditor client files.
