You may need to use a tool called DpFileList Generator to ensure the game recognizes the new .cpk patch files.
New graphic menus, eFootball-style intros, updated player faces (including young players), and new kitpacks.
Since part05.rar is just one piece of a larger set, you cannot use it alone. Follow these steps for a successful installation:

Many patches require a separate "Edit" or "Option File" to be placed in your Documents folder ( Documents\KONAMI\Pro Evolution Soccer 2017\save ) to finalize team names and transfers.
