CustomersManagment OML

I can't find the CustomersManagement OMl, so I'm not sure it installed on my computer. I had some installation issues, so Miguel actually installed from his PC. Where can I get to that OML to continue training?

In the 5th module - "Data Modeling, level 1" - of the Certification for Associate Developer online training course (Associate Developer). See the attachment to this reply, please.
