Thanks for getting in touch.
I do still have an older version of TuneSpan available on my site that works on 32-bit computers.
You can see below the "Available on the App Store" badge, there is a "Show TuneSpan Demo/Trial" link. Click that to reveal the download link.
That version of TuneSpan should be fully functional, but I am no longer supporting it in the ways I'm supporting and updating the version on the Mac App Store. And the Mac App Store version has come a long way since that old version. But, the basic moving files and updating locations in iTunes is essentially the same.
