I have a new server onto which I have installed Windows Server 2008 R2 Enterprise. I have not been successful at installing SQL Server 2008 Enterprise on it. After many attempts, I continue to get the following error message:
Microsoft .NET Framework 3.5 installation has failed.
SQL Server 2008 setup requires .NET Framework 3.5 to be installed.
I got my copies of Windows Server 2008 R2 and SQL Server 2008 Enterprise through my MSDN subscription.
Upon first installing WinServer2008 R2, I notice that the .NET Framework 3.5.1 is not installed and is not available as a feature to add through the Programs and Features control panel.
