When I ty to start Thunderbird an error-window pops up, saying:

C:\Programm Files (x86)\Mozilla Thunderbird\thunderbird.exe

Die Datei oder das Verzeichnis ist beschädigt oder nicht lesbar.

(The file is damaged oder not readable)

What to do? Can I simply download & install a new Thunderbird version? Had the same problem with pdf-files and a new installation of adobe reader helped. Did run Ccleaner freeware yesterday after quiet a while and now this problem occured for the first time. Btw: I also get this error-window:

C:\Users\Enver\AppDataLocal\HostAppService\Engine\HostAppServiceUpdateManager.exe Die Datei oder das Verzeichnis ist beschädigt oder nicht lesbar.

(The file is damaged oder not readable)

Thanks for helping!

I've just downloaded TB to my new laptop and it has loaded version 128.6.0esr (64-bit) with About showing 3 extra notes:- Nebular icon, Thunderbird is up to date and 'You are currently on an esr update channel'. The layout looks way too much like Outlook for my liking so I checked my out laptop and About shows it to be 115.18.0 (32-bit) with Supernova icon, Thunderbird is up to date and the same 'You are currently on an esr update channel'. So, how do I get TB on the new laptop (currently showing 128.6.0esr (64 bit) to be, or at least have the same layout as, my old one showing 115.18.0 (32 bit) that I know and love? Thanks Chris

p.s. I can take screenshots of both layouts if necessary but if I can get to the same version first that might solve the issue.

I am getting stopped, dead cold, every time I try to install Thunderbird mail on Linux Mint 22. I've attached a generic article that explains how Akamai's site security services bots are working to protect a site or sites that TB must access to complete it's installation task. In my case it's Comcast/Xfinity. Accordingly, TB installations will not complete and new users are locked out...some for months. The concensus of the devs that have been working on this critical issue is that there is nothing on a new TB user's side that in any way causes or contributes to the issue. I would very much appreciate any information you can provide about a speedy resolution in the works.

Note: The error notification screen "Access Denied" is the same message I get, but with Xfinity referenced.

Thanks. Wiley Oregon, USA

I have a problem with the 64-bit to 32-bit installation. (It created a duplicate for me), I uninstalled everything properly and reinstalled Today my computer does not recognize version 32 in default mode and I need it for my accounting software. We checked the registry keys, the settings ... everything is ok Thanks for your help.

Hello,

I received a new laptop with Ubuntu 24.04 and I'm trying to install Thunderbird. I have tried snap, flatpack, the downloaded package and nothing works. The only one that worked so far is https://www.omgubuntu.co.uk/2024/08/install-thunderbird-deb-not-snap-in-ubuntu-24-04 but this results in a different (?) thunderbird being installed, thunderbird-esr and there is no icon in the dock and I cannot pin it in the dock, which is a bit annoying. I saw there are other people having the same issue as me https://ubuntu-mate.community/t/cannot-install-thunderbird-because-it-is-not-allowed-by-dot-thunderbird-plug-rule/28878/13 https://askubuntu.com/questions/1538919/ubuntu-24-02-error-installing-thunderbird

The command `$sudo snap install thunderbird` gives the following error `error: cannot perform the following tasks: - Mount snap "thunderbird" (609) (installation not allowed by "dot-thunderbird" plug rule of interface "personal-files" for "thunderbird" snap)`

I also tried various commands offered in response to the questions linked above `$snap connections thunderbird` returns `error: snap "thunderbird" not found`

`$snap interfaces | grep personal` returns `119::personal-files firefox:dot-mozilla-firefox 'snap interfaces' is deprecated; use 'snap connections'.`

`$snap version` returns `snap 2.67 snapd 2.67 series 16 ubuntu 24.04 kernel 6.8.0-51-generic`

`$snap list --all thunderbird` returns `error: no matching snaps installed`

I also tried via the Ubuntu "App Center" and the Install button just keeps coming back. I expect it's running into the same error I have via the terminal and doesn't give any feedback in the graphic interface.

Please let me know what I must do to install Thunderbird via snap.

Thank you, Caroline

The pc is a new Dell 8960 running windows 11 home. I installed t-bird from the microsoft store ver 128.5.2. I needed to do a system restore and when it was done Thunderbird.exe was gone. The link that I used to open it went to c:\users\username\thunderbird.exe but there was nothing there named Thunderbird after the restore.

I found Thunderbird at "C:\Program Files\WindowsApps\MozillaThunderbird.MZLA_128.5.2.0_x64__h5892qc0xkpca\VFS|ProgramFiles\MZLA Package Root\Thunderbird.exe" I made a shortcut to that but the response is "Windows cannot access the specified device, path, or file. you may not have the appropriate permission to access the item."

I do have a current copy of the profile.

[Note: I characterized this question as an "Installation and updates" issue (even though it is not per se about initial installation or updates) because moving a profile involves installation issues.]

Recently I moved my TB profile, for the second time in the past few months. This time I paid closer attention, and noted several things of interest (that may touch on some questions that remain undiagnosed in this forum):

1. TB took longer to start up, as it could find none of the folders cached in folderCache.json, so rebuilt the cache from the new profile location before starting. (I only learned about this from the next effect.)
2. The "Move to" "Recent" folders list was empty; this cached list only gets rebuilt from use (that is, from moving messages manually (not via filter) to destination folders). This effect led me to folderCache.json- and also may suggest why the OP in that question could not get resolution of his problem.
3. The newly cached folderCache.json was 528 KB, compared to 365 KB at the old location -- and that, in turn, was 170 KB larger than the 195 KB size of folderCache.json at the original location. So each time the cache is rebuilt it grows perhaps 150~200 KB (size depending on the many-times-repeated path length).

What causes the file growth? Because each time it is rebuilt, TB checks through all of the cached folder paths, apparently guided by the mailboxes listed in folderTree.json (see image below). [I think TB just checks each path to see whether it is compatible with the current profile location. If yes, the path is cached for runtime; if no, the path is repopulated from the current profile location (which takes most of the startup time).] But TB never deletes the no-longer-valid paths; it just appends to what was already in the file, so that the list of cached folder paths just grows (thereby increasing TB's startup time, every time). The best way to get rid of the old stuff is just to delete folderCache.json and let it rebuild on the next startup, to reduce the time needed for subsequent starts.

Finally, my questions: In addition to folderCache.json (different timestamp in each profile, of course), there are four files which are the same in all profiles: folderCache-x.json, x={1,2,3,4} (see screenshot). These are apparently from actions prior to the profile relocations, as they are simply copied from one profile to the next, unrelated to changes in folderCache.json. Can someone tell me:

1. What actions cause the creation of folderCache-x.json files?
2. Why folderCache.json merely appends new folder paths without deleting the old ones?
3. Why folder paths are specified explicitly (fully qualified) rather than relative to the profile path?

Thanks for any pointers.

trying to install thunderbird on a new laptop. got the donation screen, donated. got the thank you screen, it says carry on and complete installation but there is nothing to install, no files downloaded and everything takes me back to the first screen and the thank you screen. I'm getting to the point of taking my donation back and just sticking with outlook!!!

I've been writing you about this for weeks! I cannot download an install to fix my years used Thunderbird. I always attempt a download from your site and it always gives the same error message: "Thunderbird 137.0.1-4 corrupt image"

I even took it to an IT repair shop and they got the same non-result. I need to repair/replace my old Thunderbird.

C-attached error message image plus my iMac OS info. There MUST be some way to successfully download a replacement. Please advise.

Greetings to all, I'm trying to install the Thunderbird email client on a Mac that is running High Sierra. I have downloaded the installation package 3 times from the Thunderbird.net website but each time I try to open one of the .dmg packages I get an error that states the image is corrupt and cannot be opened. Is there something I'm doing wrong?

Hi, I've successfully downloaded and installed Firefox on my HP laptop with Windows 10 and now attempting to download and install the Thunderbird email client. On Thunderbird.net when I click the Download button, the Donation Page pops up (and I made a donation) then closed that window. I'm then on the Thank You page but there is no prompt to install, so just stuck on the Thank You page. Thunderbird is not appearing in my downloads file. Can you please help?

I am attempting to install Thunderbird on a new laptop and move personal folders from old to new PC. The installation process finds my email address and ISP information but fails with incorrect password.

Steps - 1. enter user name 2. enter email address 3. install finds correct ISP information 4. accept ISP information without changes 5. enter email password 6. process popup say incorrect user name, ISP info or password 7. login to ATT.NET successfully which indicates to me that the userid and password are correct for email account.

what other information could I supply to assist with problem resolution? I do not know what to do next.

Thank you, Neal

I have a new HD and installed Linux Ubuntu 24.04.1 LTS. I installed Thunderbird version 2:1 snap 1-Oubuntu3. The program will not open Just get "Your Thunderbird profile cannot be loaded. It may be missing or inaccessible."

This has been re-posted. In error my first post said ‘Firefox’ NOT ‘Thunderbird’.

Hi all. I recently had a terminal problem on my Win 10 computer so have bought a new Win 11 machine. I ran Thunderbird mail on the old Win 10, had 5 email accounts, had about 12 local folders and had my Profile stored in a folder on the desktop. The folder was moved there some years ago but don 't remember how I did it. I moved it there because this folder gets backed up every night.

So, I have managed to remove the HDD from my old machine and have located the 'old' profile folder. I now need to re-install Thunderbird on the new machine and match it up to my old profile folder (I think...)

Any advice on how to do that?
