I just installed Windows Server 2008 Standard SP2 on a Dell T710 server. I also am trying to install SQL Server 2008 Standard on the server. I keep getting an error that it requires .net framework 3.5 prior to installation. I have installed .net framework 3.5 sp 1, several times. I installed Windows installer 4.5 and I am still getting the problem. I know this is a problem because I have been researching it. But nothing I find seems to help. I am desperate, please help.
