Supporting Internationalized Domain Name (IDN) on Windows XP requires "Microsoft Internationalized Domain Name (IDN) Mitigation APIs", whose file name is idndlpackage.EXE, but the download link is now unavailable on the Microsoft website. Where else can I download it?
idndlpackage.EXE is an archive containing 3 arch specific installers = but you only need idndl.x86.exe, which was sometimes added with redist packages with some app installs.
Search on google shows this working link:
