SketchUpFX and AO on several versions of SketchUp

I have several versions of SketchUp on my computer. For various reasons I us 2014, 2016, 2017 and 2018. Can I install FX and AO on more than on version. If so, how is that done?

Just install them on all versions, then start any of the SketchUp version and activate. It will be automatically activated in all versions.
