@starwatcher said in pso2 Steam Error :5:
Hello, please can you explain it with pics??
I think I'm doing something wrong
Launch your game with Steam in first, let it display the error message, but don't close it.
Next, go to the game folder in "*Steam\steamapps\common*", open the PSO2 folder and you will find a folder named "pso2_bin". Right click on this one and select "Properties". When the new window show up, go to the tab "Security". Next click on "Advanced", and on the new window, don't touch anything, except the checkbox at the end for replace all authorization entries. Press "Ok" and wait till it's done. After that, go now on the game who's not closed, and press "Back" on your error message.
Now, don't launch the game, but repeat all the steps, but don't open PSO2. When it's done, close everything and if that work correctly, the update will begin.
