I have gotten this "unable launch older version on profile" error dialog several times, but what frustrates me is that the dialog window only offers 2 options: exit or create a new profile. I don't want to either. I want to upgrade Thunderbird to the current version and use my existing profile (which is on a mapped drive shared by multiple laptops). [And it's so picky, one system was on Thunderbird 68.9.0 and the other 68.1.x. We are talking about tenth version changes].

There was a workaround: create a new profile, blow away all the stupid prompts for accounts etc (I really don't want a new profile), upgrade Thunderbird, close Thunderbird, open Thunderbird using my existing (and forwarded versioned profile). But what a painful work around for nothing my fault.

Sorry, just had to vent.

Chosen solution

Start TB from the command line like this: Win+R, type thunderbird.exe -p --allow-downgrade That will launch Profile Manager where you can select a profile that has previously been opened in a newer version.
