Installation errors may occur because the security certificate updates that are required to install some Visual Studio components cannot be applied to this computer. This can occur when you are not connected to the Internet or when a group policy setting on your computer prevents Visual Studio from automatically applying the security certificate updates. If you choose to continue, some Visual Studio features may not work as expected. For more information, see http://go.microsoft.com/fwlink/?LinkId=317796.
