A) Is that really version 5 point 7, or is it version 52.7.0?

B) You refer to "Secure mode". Is that actually Mozilla Safe Mode? http://kb.mozillazine.org/Safe_mode

Version: 52.7.0
Yes, Safe Mode

Clear the browser cache and the Windows Temp directory.
Download a new copy of the full installer from http://www.mozillamessaging.com/en-US/thunderbird/all
Delete the directory C:\Program Files\Mozilla Thunderbird (or C:\Program Files (x86)\Mozilla Thunderbird
Run the installer.
