I am trying to update my Witcher 3 version to 1.12 (I have it set to manual update) but whenever I try it tells me im "not authorized" and fails. I have read about other problems exactly like this one where the solution is to buy the free DLC pack. Ive already done this and It hasent helped me get authorization. any help is appreciated.

it's not much to go on, if you are double clicking an exe file, try right click --> run as admin
