Pro 100 driver installation fails on Mac OS Sequoia or Tahoe

I have a PIXMa Pro-100 printer. The Canon driver, PrinterDriver_PRO-100 series_165000.pkg will not install for me on any of my Macs, running Sequoia or Tahoe. During verification the installation fails, giving me a message to contact the software developer. I have, of course, tried the easily Googleable solution—I uninstalled all existing Canon software, restarted my computer and tried again. Several times. I re-downloaded the package, in case something got corrupted en route. Nothing works. I can only print using ancient drivers on a computer that still runs Lion OS. Any insight would be appreciated. Thank you.

Hi,
This sounds super frustrating. Have you tried downloading the driver from the Canon site https://www.usa.canon.com/support/p/pixma-pro-100?

That''s bizarre. When I went to that page yesterday and this morning the newest version it would show me was 16.5.0, no matter which OS version I chose. I tried every pull-down menu on the page. But when I clicked on your link just now and selected Sequoia, it showed me 16.5.90.1, which installed successfully. Thank you! The internet is occasionally mysterious.
