FYI, I had almost the same question a year ago when I was thinking of updating from PSE 14 to PSE 2019. I got the same answer. After a few weeks, I decided that I no longer needed PSE 14 so I deleted it using Revo Uninstaller. There are obviously some common components between PSE 14 and PSE 2019 because after deleting PSE 14, PSE 2019 stopped running and displayed error messages about a missing "Application Manager" program. The Help link on the error window was absolutely no help at all. It took almost a week for me to find an old forum link to the Application Manager download which fixed the problem. FYI!
