Well, here on Oct. 27, 2022, I'm going to recommend a slightly different approach than any of these given so far. I have versions 13, 19, 20, 30, 31, and 32 installed on my PC. The reason for this unique solution is that Rockwell changed their license validation scheme a while back and the new one breaks more easily.
What I have found is that if you install an older one with the older validation method, the new validation method doesn't install. So, for this reason, I install version 20 first, and then go from newest to oldest (to avoid re-installing all of the components over the top of each other). Going from newest to oldest turned a job that used to take more than a day into one that takes 3 hours or less.
