New drivers are required for Meta Quest Link

I've updated to the latest, non-beta for both the newly named 'Meta Horizon Link' software as well as the Quest 2 now on v83.0.

The Meta Horizon Link software doesn't seem quite finished and ready for prime time.

I have a persistent beam across the top of the app stating "New drivers are required for Meta Quest Link. Update now" - When I click "Update now", the app shuts but nothing more happens. I've waited several minutes thinking it might be doing something silently - it isn't.

I then reopen the app which is a preceded by a 'Repair' screen. Getting back into the app, I see that same "Update now" button, click it but now it fails because the required services were stopped in the previous attempt.

I restart the services and then the app, click the "Update now" button and we're back to point 1 with it closing the app and nothing happening.

I've tried completely removing the app and its registry amends using Revo Uninstaller so I can completely start with a clean slate and the issue persists after a reset and re-installation.

Is there a download url to the most recent link driver outside of the app available?
Or is this a false notification due to a naming mismatch between the link driver and the newly named Horizon Link software?

Many thanks in advance.
