Hi, Has anyone tried the FreeDV GUI 1.2 software on Windows 10? I have one report of it "not starting". Not sure if it's the 32 or 64 bit version. I understand there is also some sort of new Windows security feature that prevents application program files being installed in the "Program Files" folder.
Richard and I run mainly Linux so it would be great to get some feedback from Windows users.
