      The .NET Framework version 1.1 redistributable package includes everything you need to run applications developed using the .NET Framework.

      The .NET Framework version 1.1 provides improved scalability and performance, support for mobile device development with ASP.NET mobile controls (formerly the Microsoft Mobile Internet Toolkit), support for Internet Protocol version 6, and ADO.NET classes for native communication with Open Database Connectivity (ODBC) and Oracle databases. It also enables the use of code access security to further lock down and isolate ASP.NET applications. For more information, read the .NET Framework Version 1.1 Product Overview.

      Important: You cannot install two different language versions of the .NET Framework on the same machine. Attempting to install a second language version of the .NET Framework will cause the following error to appear: "Setup cannot install Microsoft .NET Framework because another version of the product is already installed." If you are targeting a non-English platform or if you wish to view .NET Framework resources in a different language, you must download the appropriate language version of the .NET Framework language pack.

      2. Do one of the following:
        • To start the installation immediately, click Open or Run this program from its current location.
        • To copy the download to your computer for installation at a later time, click Save or Save this program to disk.
    • Server Installation Requirements
      If you have been directed to do a server installation, you must have the following software installed in addition to the typical installation requirements:
      • Microsoft Data Access Components 2.6; Microsoft Data Access Components 2.7 SP1 is recommended. This is for applications that use data access.
      • Internet Information Services (IIS) version 5.0 or later. To access the features of ASP.NET, IIS with the latest security updates must be installed prior to installing the .NET Framework.
      • ASP.NET is supported only on the following platforms: Microsoft Windows 2000 Professional (Service Pack 3 recommended), Microsoft Windows 2000 Server (Service Pack 3 recommended), Microsoft Windows XP Professional, and Microsoft Windows Server 2003 family.

      Note: Most users will perform a typical installation and can ignore these requirements. If you are unsure which type of installation to perform, meet only the typical installation requirements.

      If you plan to develop .NET Framework version 1.1 applications, the Microsoft .NET Framework version 1.1 Software Development Kit (SDK) includes everything you need to write, build, test, and deploy .NET Framework applications—documentation, samples, and command-line tools and compilers.
