Hello @moo,
Thank you for taking time to post this issue in Microsoft Q&A forum.
Found setup instance xxxxxxxx but not in launchable state.
"not in launchable state", looks like the setup instance is not in launchable state, it might be blocked.
Is there any previous installation process paused/stopped(not completed)? I may suggest trying to confirm this in VS Installer(complete the paused installation).
It seems that there’s more than one extension to install, is it possible to try to install them one by one, I mean separately?
I also suggest trying to restart your machine and reinstall the extensions.
BTW, if it’s acceptable, perhaps reinstalling Visual Studio and then reinstalling the extensions works.
Best Regards,
Tianyu
