The Windows download is marked for 10 and 11 because I know it works on these. Not knowing if it does on 7, I will make no promise that I can't keep.

I'm glad to hear it works on 7 too.

As with any software relying on 3rd-party libraries, the challenge is rather to ensure each and every one of them keeps working on platform XYZ. The most potential I see for breakage is from Gtk, which behaves already unreliably on Windows in some contexts, and as many FLOSS projects, lacks dev and beta-testers on Windows.
