On Windows 10, latest version of Windows Defender (as 26 May 2017) block Thunderbird updater. If Windows Defender is disabled the installation is ok. I tested this on 3 computers. The installation was ok for previous versions.

Since this is an issue with Windows Defender, the only other workaround other than disabling Windows Defender, is to Download & install the latest version of Thunderbird.
