I am getting the error in the picture when I try to run WeatherLink on my imac. It used to work ,but not anymore. I did write Davis and I thought I read somewhere someone had the same problem. I tried all the usual stuff, someone said to right click on the app and get the info and then change the compatibility, or the bit setting and of course that doesn't work. you can get the info,but none of the extra stuff is accessible. I suspect that when High Sierra comes out things might be resolved with regard to Java.
