I had Thunderbird 128. I want to install Thunderbird 115. I uninstalled 128 and tried to download 115. The download is always 128. How can I resolve this?

Before you even consider this be aware your existing profile of contacts and settings will not go backwards with you. See https://support.mozilla.org/en-US/kb/dedicated-profile-thunderbird-installation

Perhaps explain why you think this is a good idea to go back. It may be you can avoid loosing your information by staying on 128.
