I am using an authenticated proxy to connect to the internet. The proxy settings are listed in Control Panel, and I get a user/password dialog box the first time I connect to a website.
While it normally works fine, when I launched a Clickonce application that needed to download files from the internet, I got this error:
Application download did not succeed. Check your network connection, or contact your system administrator or network service provider.
I went into the log file, and found this:

I've added the credentials to the "My Credentials" section in user settings, but it still did not work.
Is there any way to download files for a Clickonce application, via an authenticated proxy?
