Hi!

I am not speaking the english, sorry...

I have non-steam version game.
I want change from "Serial Number" to "Serial Number for seam"
Can I do that?

thank you

I don't think you can do this. The Steam copy is separate from the retail copy, so a different serial is required. Is there a reason you need the Steam copy?

If you delete the files you can still recover them from here later:
