Make me understand Serial Numbers and where they go for MPCX

I'm currently logged into iNMusic and I see serial numbers under certain groups of plugins but where do I copy and paste these serial numbers so I can use them in Standalone and Desktop? I know it's a dumb question but I Appreciate ALL feedback. Thanks.

Just log into your inmusic account on your standalone MPC in MENU > PREFERENCES > ACTIVATE PLUGINS and once logged in you have hit 'activate' next to the plugins you have a license for. No serial necessary.

Do the same in the MPC Software (PReferences > Activate plugins)

And for VST versions, log into your inmusic account within the plugin itself.
