One of our readers told us that after the game crashes, he uses the game integrity file verification but he gets the message 1 file failed to validate and will be reacquired every time.
Thus, the Verify Integrity of Game Files option doesn’t fix the game crashing when that error message pops up.
What does it mean when 1 file failed to validate and will be reacquired?
During the game integrity verification, Steam goes through a process of comparing all the files from your installed game to the one on the server.
The error thus means that during this verification, one of the files was not on par with the original one and fails the verification.
