Version 4.3.1

Note: Modifications made to the Duo Authentication for Windows Logon version 4.3.1 installer result in direct upgrades from version 4.3.0 to version 4.3.1 leaving the program information for 4.3.0 visible in Add/Remove Programs and the registry. This does not affect the installed 4.3.1 application's operation. See the Duo for Windows Logon FAQ for more information. - Restores the ability to perform a silent install without providing application information in the command. - Corrects an issue where the exe installer did not retain the existing FailOpen value during upgrade from a prior version. - Corrects installer issues with uninstalls and reinstalls of the same version. - Corrects an issue where a trusted session was erroneously invalidated. - Corrects an issue where the login button was focused on by default instead of the passcode field. - Adds the MaxBootTimeDelta GPO setting.
