PSE 2022 upgrade
I am running PSE 11 on an external SSD with MacOS Mojave. My main SSD (replaced) in my old MAC from 2012 is running MacOS Catalina. In order to use PSE 11 I need to restart my external SSD which is a hazzle all the time and I don't have access to all files. To be able to use PSE again on my main SSD I found a PSE2022 upgrade version on Ebay which is compatible with Catalina. The question, do I need a physical PSE 11 version on the main SSD to install the upgraded version PSE2022 or is having the serial number of PSE 11 enough? I have asked Adobe helpdesk but they refuse to help me. Thanks
