Download Capture One Express 12

Hello everybody. I recently purchase a Sony camera and I  downloaded the Capture One Express for Sony cameras. 

I´m using macOS Sierra (not compatible with 64 bits software), so the Capture One Express 20 downloaded only works for next generation macOS ( High Sierra, Mojave, Catalina).

I do a search in Google and I find that the Capture One Express 12 works for macOS Sierra. Is there any link to download the Capture One Express 12 for Sony.

Thank you very much in advance!!!
