When you get the error message, stop right there! Find the file, mentioned in the error message, and open it in a plain text/hex editor (not sure if Notepad or Wordpad will do; try a proper file manager: FAR Manager or Total Commander). Does it start with the string "K*" and end with the string "DKNJ"? Wanna give us a screenshot showing the beginning and the end of that RTP patch file?
(By the way, wrong forum. Moved.
