Like someone else said a year ago, all I get is a "no such file exception" any time I try to add a game. I followed all the steps in the Read Me text. And I get the error. Tried the x64 and the x32 options it gives me. Pity because I really needed the Better Icons for AC Origins for Steam.
I don't know if it's a program (itself) error or a user (me) error.
