Normally I would just sign on with the same account and install, but the app in question is discontinued. (BBC News app, apparently the BBC objected that 'just some guy' could make a better app than they can, in fact after 2 years they still don't have one) It still exists on one of my computers but can't be installed from the store anymore. What's involved in copying it? Not trying to break DRM, as the same MS account is on both machines.
