I've installed .NET Framework 3.5 SP1 and windows installer 4.5 (which is what I found on line as a resolution) and I'm still getting the error:
Microsoft .NET Framework 3.5 installation has failed.
SQL Server 2008 Setup requires .NET Framework 3.5 to be installed.
What operating system because in Vista I think the framework comes with service pack but I could be wrong.
