When I try to open Thunderbird I get this message: Platform version '31.3.0' is not compatible with minVersion =31.4.0 maxVersion =31.4.0. What can I do?

I tried some of the instructions for opening in Safe Mode but to no avail.

my first suggestion would be to reinstall. No uninstall, just run the installer again to replace any corrupted files (it sound like something may well be corrupted.)
