Notes
To check the version of RDB you are on, from within the application look in the top right under Help, About.
If you are not on 6.7 please book an update using the steps in this article and proceed here only after that is complete.

This procedure involves installing software, so you will need suitable privileges on your PC to be able to complete it. This desktop application update does not need to be rolled out to all users at once, as different Service Release versions can run on different computers.
