www.drstephenfox.com Posted October 12, 2019 Share Posted October 12, 2019 is this the 32 vs 64 bit problem?? 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. Link to comment Share on other sites More sharing options...
JDMvW Posted October 26, 2019 Share Posted October 26, 2019 I'm still back with lots of older software, so I'm thinking that I will stick with High Sierra until the time comes to update the computers, themselves. I can live with it better than spending a fortune on new software and lots of time learning how it works It took me a while to break with MacOS 9 as well.

peter_c5 Posted October 28, 2019 Share Posted October 28, 2019 This is exactly the problem I’ve just had! Not only did DPP4 not work properly, several other programs didn’t either - including the latest HP software I use for my (non photo) printing and scanning. I had to get Apple to reinstall the previous OS. I guess we’ll all have to wait till everyone, including Canon, updates their software. Link to comment Share on other sites More sharing options...
john_sink Posted October 29, 2019 Author Share Posted October 29, 2019 In Catalina if you go to "systems report" in "about this mac " then to "legacy" it will show the 32 bit programs that will not work. I have Epson scanner with all 32 bit programs. Link to comment Share on other sites More sharing options...
tomspielman Posted November 2, 2019 Share Posted November 2, 2019 In Catalina if you go to "systems report" in "about this mac " then to "legacy" it will show the 32 bit programs that will not work. I have Epson scanner with all 32 bit programs. You can also do this in Mojave so you don't have to wait until the apps won't run. :). If you go to the system report and click on "Applications" it will list all the apps. There will be a column for whether they're 64 bit or not, - which you can sort by. I'm holding out for now because I don't want to upgrade MS Office. Link to comment Share on other sites More sharing options...
