I'm being asked to download the latest version, but I have the latest version.

When I open TB some days, I get a message saying I need to download a new version, but I have the latest version. Is it because it's version 32 bit, and my OS is 64bit? Please see attachment.

Please follow these instructions.

Exit Thunderbird this is important.

Access: C:\ProgramData\Mozilla\'updates'

the 'updates' folder will contain folders named, e.g. F71A7C8BDDD23FE7 In that e.g. F71A7C8BDDD23FE7 folder, you will see:

  • an 'updates' subfolder
  • an 'update-config.json' file
  • an 'updates.xml' file

Note that there may also be folders named, e.g. E7CF176E110C211B, which contains the same data for Firefox. So check contents to know which is the one for Thunderbird. If you open the 'updates.xml' file in a text editor like Notepad, you will see something like:

<updates xmlns="http://www.mozilla.org/2005/app-update"><update <="" appversion="68.1.2" buildid="20191008153335" channel="release" detailsurl="https://live.thunderbird.net/thunderbird/releasenotes?locale=en-US&version=68.1.2&channel=release" displayversion="68.1.2" installdate="1570763021584" iscompleteupdate="true" name="Thunderbird 68.1.2" p="" xmlns="http://www.mozilla.org/2005/app-update"></update>

which indicates the update info for Thunderbird 68.1.2.

Move the 'updates' subfolder and the two files, 'update-config.json' and 'updates.xml', to a backup location like Desktop. You can delete them later once finished.


Access: C:\Program Files\Mozilla Thunderbird Delete 'Mozilla Thunderbird' folder to uninstall program Empty the Recycle Bin.

Restart the computer in 'Safe Mode with Networking' mode.

Download the full installer from https://www.thunderbird.net/thunderbird/all/ and run it. This will update your existing installation to the latest release version. Make sure you select the 'windows 32bit' version.

Restart the computer in normal mode.

After doing the above please report back on results and tell the forum what Anti-Virus product you use eg: is it Kaspersky ?

Um, that's a lot to do, when it says I already have the latest release. Can you please explain why I need to do all that?

And will I need to backup my addresses before I do this?

If you're using Kaspersky, you don't have to touch anything for TB, but make some adjustments in Kaspersky:
