Thunderbird Error Message : Authentication Error : Unable To Log in at Server. 150 will not install

I have been using the same Email Address and Thunderbird for Downloading my Emails for over 10 years. Now Thunderbird will Not Install. Am getting a strange Error Message ... Authentication Error : Unable To Log in at Server. This has happened on 3 machines. Why is it now impossible to Install Thunderbird on Windows 10 machines.
