Swapping from Steam to non-Steam client?

[Renik]

There's an official steam message linked somewhere in the forums, it says that only steam expansion works with steam ARR, if you can link bot versions on your account and the game updates itself with the expansion data that could work, but it's not likely, there's always some kind of installation involved, and i don't use steam for ARR so i don't know if you can link PC and steam-PC codes to the same SE account.

Wait for an official response here, and if you don't get it, contact with SE support.
