Avogadro 1.2 worked until mid December 2017. Now trying to start, instantly closes. No splash screen, no interface, no process running at all. I really liked 1.2, would really appreciate help of any kind.
Avogadro 2 does work, however , for me, 1.2 was much more intuitive, and, generally easier to use.
My windows version is 17074.rs_prerelease.180106-2256
