Can anyone help with this error? Started happening after Sierra update.

The software is not compatible with Sierra. Uninstall it and check if there is a Sierra compatible version available.
Argh, you're right 😊 I had it confused with something else. It's part of the Address Book resources. However, the advice from Apple in an identical case was to reinstall the operating system 😟 which the user did and reported it fixed the problem 🙂
See this Apple Support article - How to reinstall macOS - Apple Support - you can either erase and reinstall if your data is backed up (Part 1) or reinstall over the top of the existing install. Personally I'd backup ALL your data first, then erase and reinstall.
hi folks
i'm getting this error after upgrading to macOS Sierra
its pretty consistent. not sure how i'll reinstall operating system!? do them mean with the mac OS disk that came with your PC?
there must be an easier way?

Isn't this part of the operating system? I would rather not re-install the whole operating system. Can you elaborate?
