KB971644 download & installation.


I have a x64 program that I'm trying to install under Windows Vista x64. However upon installation receive an error message that KB971644 (Platform update) is required.

I'm not able to find KB971644 for download on the Internet. Some of the instructions show to run windows update, however windows update doesn't list a KB971644 for download and installation.

Hi albertz:

If you're still looking for help with the KB971644 platform update, please see caweclark's thread Unable to Install Update in the MS Answers forum.

KB971644 is not available for download from the Microsoft Update Catalog but all four of the updates bundled inside that platform update (KB971512 / KB971513 / KB971514 / KB960362 - see Description of the Platform Update for Windows Server 2008 and the Platform Update for Windows Vista) were installed on most Vista machines back in October 2009. If you are trying to install a Kodi media player on a Vista SP2 computer the workaround suggested by michael_corban in post # 37 of Kodi 17.1 Installation Problem with KB971644 Vista x86 to run the installer in Win XP SP2 compatibility mode allowed caweclark to run the Kodi v17.6 installer to completion without prompting for KB971644.
