SUMMARY

Learn about the two types of Microsoft .NET Framework 1.1 installation packages: Optional Component Manager (OCM) packages and Microsoft Windows Installer (MSI) packages. The package type that you use to install and update the .NET Framework 1.1 depends on the operating system that you are running. This article contains a comprehensive list of Microsoft operating systems and the .NET Framework 1.1 installation package type that you must have to install and update the computer.

INTRODUCTION

This article describes the two types of .NET Framework 1.1 packages and the type of package that you should use to install or update your computer. The following two variants of .NET Framework 1.1 packages exist:
  • Optional Component Manager (OCM) installation and update packages
  • Microsoft Windows Installer (MSI) installation and update packages
OCM installation packages are installed automatically when the operating system is installed. MSI installation packages are installed separately. Typically, MSI installation packages are installed by downloading the MSI package from the Microsoft Update Web site.

You cannot install a .NET Framework 1.1 MSI package on a computer that has the OCM version of the .NET Framework 1.1 installed. The reverse is also true. You cannot install an OCM package on a computer that has the MSI version of the .NET Framework 1.1 installed. Therefore, when you install or update the .NET Framework 1.1, you must make sure that you download and install the correct package type.

Typically, .NET Framework 1.1 OCM update packages include the operating system name in the update name. For example, "Update for Windows Server 2003" is an OCM update package for Microsoft Windows Server 2003 (32-bit). However, .NET Framework 1.1 MSI update packages typically include the .NET Framework version number in the update name. For example, "Update for .NET Framework 1.1" is an MSI update package that applies to several operating systems.

You can use the .NET Framework 1.1 language packs with the OCM and MSI installation packages. You can also use the .NET Framework 1.1 Software Development Kit (SDK) with the OCM and MSI installation packages.

MORE INFORMATION

The following sections specify the .NET Framework 1.1 package type that is supported on each operating system.
