The installer must be run on a machine that meets the .NET Framework requirements of the module being installed. The installer checks for the required version of the .NET Framework and, if it is not installed, the installation will exit. The .NET Framework is not installed by the installer if it is missing.
Module requirements can be found in the installation chapters of the corresponding module reference guides. The .NET Framework can be obtained from the Microsoft Download Center at http://www.microsoft.com/downloads.
