Email Program and DaZzle

I use DaZzle from stamps.com for my postages. Since yesterday, I get this message when I try to send a shipping confirmation email to my customers. Never happened before. I've been using Thunderbird basically seamlessly for the past 14 years.


There is no email program associated to perform the requested action. Please install an email program or, if one is already installed, create an association in the Default Programs control panel.

DaZzle was unable to start your e-mail client - you must have a MAPI compatible e-mail client for this future.

Can you help?

Thank you Steffen

This can often be corrected by downloading and running the full installer for the exact same version of TB that's currently installed:
