Hello @ibalgin_ thanks for reaching out to us.

If you see this message when launching the game from Steam >>
"There was a problem authenticating the ownership of this product"

This usually means the game is connected to either a different Steam account or a different Ubisoft account.

  • Do you have more than one Steam or Ubisoft account?
  • Are you signing in with the correct accounts?
  • Have you linked your Steam and Ubisoft accounts together?
  • Have you purchased the game and DLC from the same launcher?

Thanks for the reply!

So DLC is usually not cross-compatible across different launchers which is why you may be seeing this error message also.

As you have 2x copies of the game on the same Ubisoft account, you should have 2x game tiles for For Honor in the Ubisoft Connect launcher - one purchased from Connect, one from Steam.

Can you check if you have 2x game tiles for For Honor, in your games library, in the Connect launcher or do you have a screenshot of this?

Thanks for the screenshot! @ibalgin_ So I've checked this and it looks as though you do not have the Steam version of the game on this Ubisoft account, which is why the tile does not show in the launcher. You can see how you have two copies of the Division though, one is from Steam and one is from Ubisoft - this is how your For Honor games should appear in your Connect launcher also.
