How to Set SeaMonkey as default mail client in Windwso 10?

I had to reset my Windows 10 installation. That was a bad idea. It essentially deleted all of my programs. I'm adding back the ones I need but I can't seem to get SeaMonkey set as the Default Mail program so Libre Office and Foxit PDF reader (and probably other applications) can't sent mail.

I gone into the Default applications and Windows offers SeaMonkey as one of the mail options so I set it. It doesn't work. I suspect I need to do something more.

Can anyone tell me how to do this?

Edit > Preferences > Mail & Newsgroups section, under the *General Settings* heading, you will find "Make SeaMonkey the default application for:".

I think you click the "Mail" button.

Google says, Change default programs in Windows 10

- On the Start menu, select Settings > Apps > Default apps.
- Select which default you want to set, and then choose the app.
- You may want your .pdf files, or email, or music to automatically 
- open using an app other than the one provided by M$.

Especially the /.mozilla/ directory in backup that directory on regular basis. The /.mozilla/ directory is in $HOME.

Especially the /.mozilla/ directory in $HOME, backup /.mozilla/ daily.

Unfortunately that doesn't work. I can select SeaMonkey but it doesn't set it and I get error messages saying no email is installed. I want LibreOffice and some other apps that have a mail to function to open SeaMonkey mail.

Under Preferences->Mail and Newsgroups in the Main Menu there is a setting to
"Use SeaMonkey Mail & News as the default application for:
Mail News Feeds"
and a second line
"Use SeaMonkey Mail & News when opening browser links for:
Mail News" with check boxes
Everything is checked but it doesn't seem to work on the computer I "Reset".

Everything is checked but it doesn't seem to work on the computer I "Reset".

I did not have that.

I have "Make SeaMonkey the default application for:".

With under this line 3 big buttons "Mail", "News" and "Feeds"
