Hello there srshowers We have read your message. We try to help you.

Check if you are running a second version on your desktop from your pc - laptop. Delete these double versions of the Thunderbird software. Also delete your current version of Thunderbird even if there isn t a double version but one version try to delete them.

Take this version of Thunderbird.

https://www.thunderbird.net/en-US/thunderbird/91.9.0/releasenotes/ Or the newer version of the Software. https://www.thunderbird.net/en-US/thunderbird/91.9.1/releasenotes/

See if this helps. https://support.mozilla.org/en-US/questions/1269873#answer-1259076

I ran the troubleshooter in Thunderbird and deleted the cache and that seems to have cured the problem. I have not been asked to update since.

I have the same problem on two computers and the chosen solution ( https://support.mozilla.org/en-US/questions/1269873#answer-1259076 ) doesn't work for me.

After that, I deleted Thunderbird completely, whit al the folders I could still find after the deleting. Freshly installed Thunderbird (91.10.0), but next day same pop-up was there again....... annoying. Any suggestions?

Since 91.x up to now 102.2.0 (64-bit) I am getting the "…can't update…" prompt and nothing that I found here seems to correct this misbehavior. There is only one Thunderbird installation on this PC. All cache, temporary files, all remains of older and 32-bit installations are deleted. There are no beta or daily parallel installations.

How do I make Thunderbird work correctly with updates?
