.NET Framework 2.0 Redistributable Prerequisites

 

Microsoft Corporation

March 2006

Applies to:
   Microsoft .NET Framework 2.0

Summary: Describes the minimum configuration requirements for a computer where the .NET Framework redistributable package is to be installed. (4 printed pages)

Note   It is recommended that you meet the minimum requirements. Failure to meet minimum requirements results in a non-supported deployment. If the minimum requirements are not met, Dotnetfx.exe setup will block the installation of the redistributable package. Specifically, note that you cannot install the .NET Framework redistributable package on a computer running the Microsoft Windows 95 operating system. It is always highly recommended that you install the latest service packs and patches for all installed programs on the computer, including operating system service packs.

Software Requirements

The following are the basic requirements for the .NET Framework categorized by server and client machines.

Server Definition: A computer that hosts a distributed application. This could be a Windows Server 2003, Windows XP Professional, or Windows 2000 computer. In many cases, these computers are Web servers running ASP.NET applications.

Client Definition: A computer that runs a locally installed application, such as a Windows application, that might also retrieve or process data from a remote database; or a computer that accesses a distributed, Web-based application. These computers are not required to serve information to other computers. This could be a Windows XP, Windows 2000, Windows ME, or Windows 98 computer.

Software Minimum Version Recommended Blocking
Internet Explorer 5.01 6.0 SP1 Required
Windows Installer 2.0 (Windows 98, Me)

3.0

3.1 Required
MDAC *   2.8 SP1 Optional, required for data access
IIS **   5.1 (Windows XP)

6.0 (Windows 2003)

Optional, required for ASP.NET
Core WMI     Optional
Note   A number of elements of the .NET Framework and underlying Common Language Runtime (CLR) rely on technologies that do not affect basic functionality, and that are delivered in optional software products or products that are not installed as part of the .NET framework or the operating system. If the optional software requirements are not met, Setup will not block installation or warn you of their absence.
*Depending on your data access strategy, you may need to ensure that Microsoft Data Access Components (MDAC) is installed on the client computers, the business servers, the Web servers or the database servers.
If your application uses the System.Data namespace, you must install MDAC on the computer to which you are distributing.
You should ensure that you deploy the same version of MDAC to the production environment that you use in development. Visual Studio 2005 ships with MDAC 2.8 SP1, so it is likely that your developers have developed and tested your solution with that version. If you subsequently deploy the application to computers where for example older version of MDAC is installed, you run the risk of encountering unforeseen problems. The latest version of MDAC is available for download at the Microsoft Universal Data Access Web site.
**Internet Information Services (IIS) on the server for Windows 2000, Windows XP (Professional), and Windows Server 2003. This is required for using ASP.NET applications. If your solution includes a Web tier, you must ensure that IIS and the latest security patches are installed on your target computer(s). IIS can be installed from the operating system installation CD or DVD, and the latest security patches can be downloaded and installed from the Windows Update Web site.
