I am encountering a message of "The installation seems to be incomplete. Please check your hardware and disk setup and/or re-install." when trying to run Thunderbird.

This first occurred on a system that had been working for a while. An update may have been installed.

Here's what I've tried. -

Uninstall Thunderbird (along with Firefox and Mozilla Maintenance.) Checked for Program Files/Mozilla folder (all were removed). Run SFC / Scannow Run CHKDSK Installed pending Windows update. Restarted the System Renamed (essentially removed) Profiles folder Turned antivirus software off Downloaded and installed the latest version of Firefox, then Thunderbird. Launched Thunderbird. Still received the same error..

Any ideas on how to resolve the issue?

On https://www.thunderbird.net/en-US/thunderbird/all/ if one were to select "Need a specific installer?" for any locale and any release channel and select "Linux" with "32-bit (binary)", then selecting "Download" means you get taken to a variety of "404 page not found" pages.

I do not need a Linux 32-bit release and I am not sure one still exists, but just wanted to report this error on the webpage.

Under installed apps I have two entries for Thunderbird: 1) 140.8.0, 2/25/2026, 244 GB (sic) and 2) 140.12.1, 7/2/2026, 250 GB. Is it safe to temove 1), and how is it possible to be that large an app?

Please let me know if it is safe to remove the older version of Thunderbird in the Installed Apps list. I also question whether the size of the app in the list is accurate; 250 GB seems quite enormous in a 500 GB hard drive. Thanks, Hans
