PS. Just tried it and it seems is does not? I got the following errors:

(a) Under firefox:

URLDownloadToCacheFile failed with HRESULT '-2147024891'

(b) under IE

System.Deployment.Application.DeploymentDownloadException (Unknown subtype)

 --- Inner Exception ---
System.Net.WebException
 - The remote server returned an error: (407) Proxy Authentication Required.
