The filenames are in ANSI format and unfortunately, this very file has a "ö" in it, which is indeed part of the ANSI typeset but might lead to problems, especially on a Chinese windows. As I'm completely unfamiliar with Chinese windows: Is there any possibility to set the language to English or German? So that the file names are interpreted correctly?
This reminds me of a lot of trouble I've had with the Japanese train simulator BVE a few years ago...just the other way round: There were Japanese letters in file names and I couldn't install some routes.
