Overview

Test Design Studio is built using Microsoft's .NET Framework.  As such, a prerequisite of Test Design Studio is that you have the proper version of the .NET Framework installed on your machine.

Test Design Studio 2.0 targets .NET Framework 3.5 SP1.

This is the latest release of the framework and includes many security and bug fixes to ensure an adequate environment for execution.  All users are encouraged by Microsoft to have the latest version of the .NET Framework even if your application targets an earlier release.

There are essentially two ways to download .NET Framework 3.5 SP1:

Bootstrapper Package

This package is a minimal download where the installer will later download only the files it needs for the upgrade.  This is the most efficient way to install the framework, but user experience has shown that the installation does not always work.  You can also have issues if your corporate environment blocks the installer from downloading the necessary files.

Full Package

This package includes everything that is needed for the installation.  The installation file is much larger than the other download technique, but this package typically installs without issue since it is all-inclusive.  This package also removes corporate filtering since no additional downloads are necessary.
