The new certificate means that any upgrades or patches previously downloaded from the web site prior to Monday May 16, 2011 will not complete if clients attempt to run them after Monday. The solution is to download the latest certified version of the upgrade or patch they want to install from the downloads page.
Users who have already downloaded the “clickonce” client components and accessed the application will be unaffected unless they clear the application cache. Anyone who clears the app cache, as well as anyone who downloads and runs the click-once components for the first time after Monday May 16, 2011 will receive a warning that the install is uncertified. To allow the click once components to run select Run and the download to login will continue.
