Thunderbird is not default email client after update 45.0.

In Thunderbird, I have checked under tools->options->advanced->General that it is set a default - it is

In Windows, Under Control Panel\All Control Panel Items\Default Programs\Set Default Programs I have checked that Thunderbird is set at the default email client- it is. One odd thing is i notice Thunderbird is missing the usual blue/white icon.

If I look under Add/Remove programs I see the previous version is still showing as it has the icon while the latest doe not have the icon. Has the update not registered itself correctly?

Chosen solution

The easy solution: Uninstall Thunderbird and re-install.

Before starting, I made sure I had backup of my profile folder, taken a note of all settings and made a copy of profle.ini.

I re-installed. T'bird used the existing profile.ini so I was back up and working with no problems and minimal effort.

I need not have=bothered with all the backup but, well, it can't do any harm.

Thx Christ1 but as I mentioned in the OP, I had already checked that.

Perhaps I should add that this was working until the 45.0 update today.

Hello. If you want set Thunderbird default email client, do all, of the above. 1. Open Start - Settings 2. Open tab "Deafult Apps" 3. Change default email app to Thunderbird. If you can't change this. Reinstall Windows. (Realy, I haved this bag too, and i reinstall windows and it worked)

Thx InfinityTime - as stated in the OP I had already checked that Thunderbird was the default.

I really, really, really don't want to have to reinstall Windows. I hope it doesn't came to that!

I think I'd try re-installing Thunderbird first.

I Just updated my Win & machine with Thunderbird 45.0.

Now I have the same problem there. This has to be a bug.
