Hi @mrg55 ,
While Trend Micro 17.7.1979 still works with Windows 7, the latest version 17.8.1192 will only be available for some editions of Windows 10 and Windows 11. The end of support day for Windows 7 was on January 14, 2020 and after this date, we can only provide limited technical support for issues encountered on Windows 7. Windows 7 users can still visit our Support Website for technical solutions or can consider upgrading to the latest operating system to stay protected.
