I collected this pic from the installation manual thread. Basically this same problem is happening to me too. Yesterday I wasted my whole day trying to download a eroge but this prob popped up every time. TIA

First try putting your system locale in Japanese, the reason is because it effects not only how the game is read but also the text in Japanese apps and if the app was in a archived re extract again.
