I recently installed the Windows 8 preview on my PC. It runs great. I am trying to install the new Sentinal software version, but it will not let me. It says I need Framework 2.0. I have no idea what that is, but I actually have Framework 4.0 installed. Does anyone know if I will be able to install it?
I assume you're referring to .NET Framework 4.0. The different versions of .NET are, to a large extent, independent of each other. If software was written to use .NET 2.0, you'll also need to install that version.
You can download the installer for .NET 2.0 from the Microsoft Web site here.
