I'm restoring my system and I can install this if I want... what is it exactly?
It's a Framework that must installed on a computer to run .NET programs such a VB.NET, C#.NET, Cobol.NET, Fortran.NET etc, etc. You most likely don't have any .NET programs using .NET Technology on your machine and you don't need it. If you ever do install an application that uses the .NET Technology using the .NET Framework and it's not there, you'll know it . Duane
