I installed Thunderbird about a month ago and was in the process of transitioning from Windows Mail. Last weekend I had a computer crash with the Microsoft BSOD. I believe this occurred during an auto update. I am running Windows 10, Home, 64 bit. I got the computer back up by using a system image backup that was slightly over 2 months old and pre-Thunderbird. Thunderbird was running fine before the crash. Now when I try to re-install Thunderbird (several different versions) I get the error message "This app will not run on this computer." As a side note another program, Libre Office, will not re-install either.
