(Edit 2: this doesn't work)Hi, it maybe very late, but better that never, I recently discovered that you need the windows Japanese package in order to the game to install right(you can find it in the language menu in your windows configuration menu, you only need the main one, not text to spech or spech to text). Edit: I almost forgot to say it, but this is because the songs name are mostly writen in Japanese, something that windows wilI not know how to write without the japanese language pack. I hope this may help.
