Since Komodo’s last release, Python 3.6 has gone end of life, and so has our “Downloads” page.
You should be using a release that is 3.8 or higher. If you have an account on The Platform, you can access the Featured Projects from your Dashboard, or create a customized Python specific to your needs.
Review the setup instructions in Komodo that talk about “Python 3”. There are some features in Komodo that can’t use Python 3, such as the regular expression editor, but that shouldn’t limit you too much.
