How to obtain Microsoft .NET Framework 1.1 Service Pack 1
This hotfix contains two types of packages: a Microsoft Windows Installer package, and an Optional Component Manager (OCM) package. If you use Windows Server 2003, you must specify that you require the Windows Server 2003 (OCM) update. If you use an operating system different from Windows Server 2003, you must continue to use the Windows Installer package. For Windows Server 2003, Windows File Protection monitors the .NET Framework 1.1 files.
To correctly install the hotfix on Windows Server 2003, you must install the OCM hotfix package. If you try to install the Windows Installer package on Windows Server 2003, you receive the following error message:
The installer cannot install the upgrade patch because the program
being upgraded may be missing or the upgrade patch updates a different
version of the program. Verify that the program to be upgraded exists
on your computer and that you have the correct upgrade patch.
