On the Visualisation preferences page (Preferences -> Plug-ins -> Visualisation) there is a means in the description block to install the 3 different AVS plug-ins that people are commonly trying to use. It won't install presets as that's down to you the user but you end up with 2.81d, 2.82 & CHAVS (which is incorrectly marked as 2.81b). That's all that can really be done as AVS is & always has been unstable.
