You may be getting this warning when you install the latest version of Jaikoz on Windows
The reason for this is that the three year security certificate being used to sign Jaikoz expired in February 2022. A new one was purchased and used to sign 11.1 and 11.2 but although Jaikoz is properly signed Windows doesn’t remove this warning until the application has been installed on enough computers, so hopefully this warning should disappear within a few weeks.
