After you uninstall some software updates on a computer that has Windows Installer 4.5 installed, some assembly files may still reflect the updated version instead of the original version of the files

On a computer that has Windows Installer 4.5 installed, you uninstall some software updates. However, after the operation finishes, some of the software assembly files may reflect the updated version instead of the original version of the files.

For example, on a computer that has Windows Installer 4.5 installed, assume that you have the 2007 Microsoft Office system installed. If you install and then uninstall 2007 Office system Service Pack 2 (SP2), some assembly files in the global assembly cache (%SystemRoot%\Assembly\GAC) remain from the 2007 Office system SP2 version.

This problem occurs because of an error in Windows Installer. This problem occurs when the software update that you remove includes a RemoveFile table entry.

This problem may be avoided for 2007 Office system SP2 if 2007 Office system SP1 is installed first. If 2007 Office system SP2 has been installed directly over the RTM version of 2007 Office system, this update should be applied before you try to uninstall 2007 Office system SP2.
