ck2 viking metal and steam problem

[reshogu]

Hello! I tried to install viking metal dlc on steam it gives me error message " Steam cannot install game crusader kings 2 : viking metal. app configuration unavailable".

Could somebody help me with this problem

This is a Steam error rather than a game problem.

Try hitting the Clear Download Cache button in Steam, then exit Steam and reboot.
