Custom Configuration

I have just installed Version 7 but, on starting the application,  I am being told

" In order to use New Structural Elements in Open Building Designer, additional content will need to be added.."  "Which Local Dataset would you like to use"

The Application point to our Organisation's Workspace. That  works as it should.

During the installation I selected the US Dataset as i have done in the past. I am not sure what local dataset I am being asked to select. None of the options provided are applicable.

I have copied the delivered Dataset_US to my organisation's Workspace but that did not solve the problem.

Am I missing a step in the installation and how do I correct the misstep.

Many thanks.
