If your 2019 or earlier versions of Intuit Pro Series (and Basic) will not open and you get a message that it is your Browser needs updated, for each year prior go to your "Start" at the bottom right of your screen and scrool down the apps to the Pro Series years there.  Under each year, use the arrow down and select "Pro Series Updates"  and follow the update instructions.  This will make your browser compatible with the software year and allow it to be opened..  I called Intuit and it now works. I tried to put a screen print but would not allow me here.
