did you try 'listaddressgroupings' or 'listreceivedbyaddress' yet? is it giving you any results?
installing new version might give you more problems because of the version differences too big
but if you insist, it's up there listed on forum's header there's a link to Bitcoin Core: 0.15.1
I tried 'listaddressgroupings' and 'listreceivedbyaddress' and neither gave any results.
