Upgrade to last compatible version

Hi, I had purchased and installed a BTT licence earlier in March 2018. However, I never realized the app does not automatically update itself. I remember when I signed up that updates for 2 years were available. I am on version 2.444.

Need help to know which is the last compatible version my licence can run with? And where I can download that version?

Running Sierra 10.12.6

Bumping this up to see if I can get some solution please?

This one should work fine with your license: https://folivora.ai/releases/btt3.346-1554.zip
