When you install multiple hotfixes without restarting your computer between each install (chaining), the correct binary may not be installed on your computer.
This problem may occur with hotfixes for Windows XP or Windows 2000 that were created before December, 2002 (even if you use the QChain.exe file or the QChain functionality included in Windows XP and Windows 2000 hotfixes released since May 18, 2001) or hotfixes for Windows NT 4.0 (regardless of when they were created).
Note To determine when a hotfix was created, view the Modified date on the hotfix installation package.
This problem occurs when two hotfixes contain different versions of the same binary and QChain.exe file, or when the hotfix installation package for Windows XP or Windows 2000 hotfixes that were created before December, 2002, obtains the file version of the binary based on the file in memory instead of the file on the disk. For example, this problem may occur when you follow these steps:
Microsoft has released an updated version of the QChain.exe command-line tool that resolves this issue. The following file is available for download from the Microsoft Download Center:

The Qchain.exe tool allows system administrators to safely chain hotfixes together. Hotfix chaining involves the installation of multiple hotfixes without restarting the computer between each installation. Without this tool, the only supported method is to restart the computer after each hotfix installation.
Note QChain functionality is included with all Windows XP and Windows 2000 hotfixes released since May 18, 2001. However, Windows XP and Windows 2000 hotfixes released before December, 2002, do not include the update discussed this article. If you are chaining multiple Windows XP or Windows 2000 hotfixes released before December, 2002, and two or more of the hotfixes contain different versions of the same binary, make sure that you use the updated version of QChain.exe that is discussed in this article.
