Need to retrieve Contacts from dead computer. Contacts were in address book of Windows Live Mail 2012

I can only find older articles on this question for some reason, and none of them give a straight answer.

I have the complete folder structure available to me from an unbootable computer.

I need to get the contacts back from a POP email account that was in Windows Live Mail 2012.

Is there a straightforward way of doing this? The system was running Windows 8 I think, but It may have been 7.
