The "GetFileVersionInfo" function for localized binary files may return incorrect file-version information in Windows Server 2008 and in Windows Vista Service Pack 1

In Windows Server 2008 and in Windows Vista Service Pack 1 (SP1), the GetFileVersionInfo function for localized binary files may return incorrect file-version information.

For example, the correct file version of the following file is 7.00.6001.18000: However, GetFileVersionInfo returns 7.00.6000.16386.

Additionally, if you use the software inventory function in Microsoft Systems Management Server (SMS) 2003 or in Microsoft System Center Configuration Manager (SCCM) 2007 to scan for required updates for Windows Server 2008 or for Windows Vista, incorrect results may be returned. This occurs because SMS 2003 and SCCM 2007 use the GetFileVersionInfo function to query file-version information.

Note This issue does not occur in Windows XP or in Windows Server 2003.

This issue occurs because Microsoft has modified how file-version information is retrieved in Windows Server 2008 and in Windows Vista.

File-version information has a fixed part and a nonfixed part. The fixed part contains information such as the version number. The nonfixed part contains things such as strings. In earlier operating systems, the GetFileVersionInfo function takes file-version information from the binary file. (This file is an .exe file or a .dll file.)

However, in Windows Server 2008 and in Windows Vista, GetFileVersionInfo queries the fixed part of the file-version information from the multilanguage file (an .exe file or a .dll file) and queries the nonfixed part of the file-version information from the .mui file. Then, GetFileVersionInfo merges the fixed and nonfixed parts of the file-version information and returns the result to the user. If a particular binary file does not have a corresponding .mui file, file-version information retrieval reverts to the behavior of the earlier operating system.

SMS 2003 and SCCM 2007 determine file version information by using the GetFileVersionInfo API. Therefore, file-version information for localized binary files is different in Windows Server 2008 and in Windows Vista than in earlier operating systems.
