.NET Framework 3.5 SP1 is a major upgrade for .NET Framework 3.5 and so it tries to remove the older version i.e .NET Framework 3.5 during the installation.

.NET Framework 3.5 is a cumulative update for .NET Framework  2.0 SP1 , .NET Framework 3.0 SP1 and .Net Framework 3.5, where in .Net Framework 3.5 SP1 is the cumulative update for the .NET framework 2.0 SP2, .NET Framework 3.0 SP2 and .NET Framework 3.5 SP1.
So during the installation of .NET 3.5 SP1, it tries to uninstall .NET 2.0 SP1 , .NET 3.0 SP1 and .NET 3.5, however it was unable to do so due to missing source file from the installer cache evident by:

MSI (s) (24:FC) [02:54:11:910]: SOURCEMGMT: Failed to resolve source

 

RESOLUTION: To fix the issue, one needs to remove the .NET Framework 3.5, .NET Framework 3.0 SP1 , .NET Framework 3.5 using the .NET framework removal tool or the Uninstall utility.
