Hotfix information

Important 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.
A supported hotfix is now available from Microsoft, but it is only intended to correct the problem that is described in this article. Only apply it to systems that are experiencing this specific problem. This hotfix may receive additional testing. Therefore, if you are not severely affected by this problem, we recommend that you wait for the next .NET Framework 1.1 service pack that contains this hotfix.
