is it impossible to get a working standalone copy of mass effect 3 on pc?

So, i played mass effect 1 and 2 long back (around 8-9 years back) i always wanted to play the 3rd one since i loved the first two but time and again I kept struggling to find a functioning copy. I got a box copy which had a code that no longer worked and bought the steam copy that basically doesn't function cause the player doesn't exist anymore. I already have the first two games on steam so didn't want to buy legendary. Is there any other option.
