Hi, I am trying to install the ADO.NET Data Services Update for .NET Framework 3.5 SP1 (http://www.microsoft.com/downloads/en/details.aspx?familyid=79d7f6f8-d6e9-4b8c-8640-17f89452148e&displaylang=en). However, I receive a message: The update is not applicable to your computer. When I look in the event viewer, I see this message: Windows update could not be installed because of error 2149842967. I have looked at various forums and been unable to uncover a solution. It definitely seems the operating systems SP1 is the source of this issue. It installs fine on Windows Server 2008 R2 servers. But all SP1 servers display this same message. Can anyone please provide any insight into this and a possible resolution? Thank you in advance. --Matt
