SmartUpdate and additional information
For flexible bulk license and contract management, a legacy application called SmartUpdate can be launched either from SmartConsole’s main menu (via the icon in the top-left corner of SmartConsole) and clicking Manage Licenses and Packages or (if you cannot log in to SmartConsole after the trial license has expired) by opening the C:\Program Files (x86)\CheckPoint\SmartConsole\R81.10\PROGRAM\SmartDistributor.exe
executable.
There is a SmartUpdate executable in the same directory, but it seems like it was supplemented by SmartDistributor in version R81.10.
