I just downloaded the upgrade. I have 2020 and 2019 on my computer and they are not affected but I am having trouble with 2021. When it installs it will ask if you want a clean install or if you want your previous work incorporated into 2021. That is not the way it’s worded but that’s what it does. The trouble I’m having is I can’t seem to get past the opening screen so I will be getting in touch with Corel.
