Can't install Battlefield Hardline in English, only Polish and Russian.

This usually only happens if you purchase out of region game keys. North American and EU versions of the game have the language packs for English but not Russian and Polish - that is a completely separate region which does not include any language packs for English.

If you somehow received an Eastern European version of the game from Best Buy. you must take the game back to Best Buy and ask for an exchange or a return - they will require your receipt for this transaction.
