I believe you may be correct about the redirect, because after I removed iTunes the first time after the problem with Outlook and downloaded iTunes, even though I'm using Windows 7 on a 64-bit computer, it downloaded and installed an older version. I am aware of the issue with using the older video card version, as the latest iTunes broke my sync with Outlook. I haven't tested yet on my one remaining XP box, but I suspect that may redirect to the 12.1.2 page rather than 12.2. The third of these - which is actually the 32-bit application with a 64-bit installer - should be used if you get a warning about video card incompatibility when you install the standard 64-bit version, but also may resolve issues with playback, QuickTime compatibility, and problems with some third-party applications (including Outlook). iTunes 12.1.2.27 (64-bit 'for older video cards') - itunes64setup.exe.ITunes 12.1.2 is the last version to work with Windows Vista (and XP) - direct links to the installers as follows:

! iTunes 12.2 requires Windows 7 or later, 32- or 64-bit (the Apple download pages are still confused/confusing with respect to this). 'iTunes will also not support 32-bit Windows computing:'
