error when attaching a file in CMS Desk
Hello, when attaching a file in CMS Desk 7 we recieve the below error.
[HttpWebRequest_WebException_RemoteServer]

Arguments: NotFound

Debugging resource strings are unavailable. Often the key and arguments provide sufficient information to diagnose the problem. See http://go.microsoft.com/fwlink/?linkid=106663&Version=5.1.10411.0&File=System.Windows.dll&Key=HttpWebRequest_WebException_RemoteServer

We upgraded from Kentico 5.5 to 7. THis is our only issue.

Thanks

RE:error when attaching a file in CMS Desk
Hello,

1. Have you tried visitng the link in the error message and install the Silverlight tools to get more details about this issue? Moreover, is the Silverlight correctly installed on the client PC? Are you using the latest version?

2. The issue is with the Silverlight control, not within Kentico. You can try to disable silverlight as the article suggests or you can try some of the solutions on the following forums:

- stackoverflow.com/questions/1243911/silverlight-will-not-load
- blog.stronico.com/2009/10/how-to-solve-unhandled-error-in-silverlight-application-code-2104/
