Update Microsoft .NET Framework

If Microsoft® .NET Framework Version 1.1 is not already installed on the client tier, the installation program installs Microsoft .NET Framework Version 1.1 Service Pack 1.

Prerequisites

If Microsoft .NET Framework Version 1.1 is already installed and it is not at the Service Pack 1 level, you must apply Service Pack 1.

For computers that operate in languages other than English, the installation program does not install the required language extensions when Microsoft .NET Framework Version 1.1 Service Pack 1 is installed.

Procedure

If Microsoft .NET Framework Version 1.1 was already installed:
1. Verify that it is at the Service Pack 1 level. See article KB318785 on the Microsoft Web site for information about how to determine the installed version of .NET Framework.
2. If it is not at the Service Pack 1 level, install Service Pack 1. You can use Windows Automatic Updates to install update KB867460, or you can download and install it from the Microsoft Web site.
If your computer operates in a language other than English, download and install the language pack for your language. The language pack for Microsoft .NET Framework Version 1.1 is available from the Microsoft Web site by searching on .NET Framework Version 1.1 Language Pack.
