This security update cannot be applied to any other editions of Microsoft Visual Studio 2008 Service Pack 1.

Note The Microsoft Download Center update KB numbers for Visual C++ Redistributable packages differ from the SMS, SCCM, WSUS and MU update KB numbers. The full versions of the fixed Visual C++ 2005 and 2008 redistributable packages (KB973544, KB973551, and KB973552) are listed on the Microsoft Download Center only as these are full new versions of the products. The updates listed on SMS, SCCM, WSUS, and MU (KB973923, KB9739234) are updates only for customers who have previously installed vulnerable versions of the Visual C++ redistributable packages. These updates are not the versions on the download center.
