This version opens with Catalina BUT the 'convert (to JPG) and save function' does not work. I have reinstalled DPP4-40 and that is the same. I have tried all my devices and that function fails to work on them all. Downloading DPP4-50 from the Canon website and trying to re-install all over again does not work - my Mac refuses to install and and refers me to the (Canon) developer. I suspect that I'll have to wait until Canon wakes up and develops a Catalina friendly version. I expect it to be a long hibernation. Oh hum. I may consider going back to Moave on my MacBook until then.
