I have been having using Thunderbird as my email package for over 10 years and lately have been having issues. I was looking to cleanup the install (version 140.5 esr) and noticed an older version of the app still exist on the computer (version 68.4). will deleting this version have any implications. This computer was originally Windows 10 but has been upgraded to Windows 11 when the problems seemed to start appearing.

Deleting 68.4 shouldn't cause any problems. What are the issues you're having?

currently having a corruption issue with Thunderbird and have some history in the messages that I do not want to delete. Just trying to cover my bases before starting to delete/repair the file. was planning to back up the main directory before deleting the older install and then try to repair the main install but not certain how to proceed with that
