I bought Starry NIght Pro 7 in February 2019.
I just uninstalled it for issues I could correct. Now intending to
install Starry Night Pro 8 I get a message that it will not install
with Windows 7 on my PC. MY ONLY use of Starry NIght is the
basic solar system viewed from 0°E 90°N of sun. What can I install
that will allow me do this?
