Turning 'on' the Get Button

Hello,

I am having trouble figuring in which location I am looking to activate the GREYED out GET button so that my engineers can access different versions that they have created.  We are still in our infancy with our vault usage and have not yet activated workflows, so perhaps my question is twofold:  A. Is the activation of this particular feature part of the Workflow. B If not, how can I do it? 

I have drawn an arrow at the feature I would like to activate, and I am thankful for all help and advice.  Cheers Alex
