There seems to be some contradictory information about support for 32-bit editions of Window 8. The standard iTunes download page for 32-bit systems excludes Win 8 in the description of 12.1.1, but immediately after says that it is compatible with the 32-bit edition of Win 8!

ITunes is the easiest way to enjoy everything you need to be entertained - music, movies, and TV shows - and keep it all easily organized. Rent or buy movies, download your favorite TV shows, and more. ITunes is also home to Apple Music, where you can listen to millions of songs and your entire music library - ad-free with zero.

Since prior to iTunes 12.1 all '64-bit' versions were actually 32-bit applications with a 64-bit installer, and these all ran on 8.1 - as does the 'for older video cards' version of 12.1.1.4 (which has that same hybrid architecture) I would assume that the 32-bit version of 12.1.1.4 should be fine for your machine. Just in case you need it, the direct link for the installer is:

iTunes 12.1.1.4 for Windows (32-bit) - iTunesSetup.exe

Just right-click on the link, select Save target as... (IE) or Save link as... (Chrome), save the file to your desktop, then double-click to run it.

If for some reason 12.1.1.4 won't install, the 11.4 installer is here:

iTunes 11.4.0.18 for Windows (32-bit) - iTunesSetup.exe

And you’ll still have access to your favourite iTunes features, including your previous iTunes Store purchases, rentals and imports, and the ability to easily manage your library.

Music, TV and podcasts
take centre stage.

iTunes forever changed the way people experienced music, movies and podcasts.

And rest assured; everything you had in your iTunes library is still accessible in each app. iCloud seamlessly syncs everything across your devices — or you can back up, restore and sync by connecting the device directly to your Mac.

The new Apple Music app is the ultimate music streaming experience on Mac.¹ Explore a library of over 75 million songs, discover new artists and tracks, find the perfect playlist, download and listen offline, or enjoy all the music you’ve collected over the years. And find it all in your music library on all your devices.

The Apple TV app for Mac is the new home for all your favourite movies and Apple TV+. Watch everything directly in the app or enjoy it offline, and discover the best of what’s on in the Watch Now tab. You can even pick up where you left off on any screen, across all your devices. And for the first time, 4K² and Dolby Atmos³–supported movies are available on Mac.

The best entertainment, comedy, news and sports shows are now available on your Mac with Apple Podcasts. Search for podcasts by title, topic, guest, host, content and more. Subscribe and be notified as soon as new episodes become available. And in the Listen Now tab, you can easily pick up where you left off across all your devices.
