I have been running afoul of a SQL Server Express 2014 Installation Rule:
This computer does not have a required update for .NET Framework 2.0 or .NET Framework 3.5 SP1 that is needed for a successful installation of .NET Framework 4 and Visual Studio components that are included in SQL Server. To continue, download and install
the required update package from http://go.microsoft.com/fwlink/?LinkID=196047. A computer restart is required after installing this update.
I have disabled/enabled .NET Framework 3.5 in order to re-install the framework to no avail.
I have attempted to install the .NET Framework 2.0 (for some strange reason) with no luck.
I have attempted using the .NET Framework Clean Up Tool Go to the complete details ...
