It should install over the newer one just fine. You will also have to reinstall older Deep Learning models.
May I ask why you need to roll back?

@TVJohn I may also return to previous version, can you report back on if your AI effects still work, and you have no problems with the deep learning module. You have to remove 20.4 models and replace with 20.2. The last time I reverted to a previous version in VP19, and reverted the models the AI effects broke
I have roll back as the Magix AVC renders are crashing V20 on the new build, did not happen in the prevoius build or V19. I am not using deep learning.
