Thanks adam. I am not an expert on IIS by any stretch, so bear with me..
What you are saying is to create a new folder on the server such as "cutesoft_client_files" and make it a virtual directory in IIS for the web in question with an Alias of "Cutesoft_Client".
Then in the web.config file, add the key you referenced. I am not sure how the "~/editor" path gets to the virtual directory "Cutesoft_Client" (which is probably because I don't fully understand the path "~/editor"). I don't see any folders called "editor" in the default Cutesoft_Client folder.
Sorry to be so dense, but I am good at it.
