Hello, I just got a "forced" update of Thunderbird. Thereafter it refuses to start, giving me the error: "Error Platformversion '128.4.0' is not compatible with minVersion >= 128.3.1 maxVersion 128.3.1" (see attached image). I am now without e-mail on my PC and am not very enthusiastic about this situation. Best regards, Greg Jordan

Just reinstall from thunderbird.net. Just occasionally these issues appear here in the forum and reinstall has been 100% effective in the past.

What happens to the e-mails I have saved to local folders and to the various settings if I do a straight re-install? Won't they be overwritten? Where do I find the local folders in the Windows 10 file system? A backup of at least my locally saved e-mails might be prudent...
