Try using 7-Zip method instead of Freearc.
Otherwise, I don't think there should be a problem if UltraARC worked on Far Cry 4, There was a 5GB file on that game, which makes it clear that it shouldn't be a problem to work on the 52.7GB file, if Cardinals were used in the program because they have a limit of 4GB, and UA worked on FC4 and there was a 5GB file it means Int64 was used and those have a limit of 9,223,372,036,854,775,808 bytes = 8 exabytes, I really planned ahead.
