Ao no Kanata no Four Rhythm Game Error

[Lucion]

Okay so, after hours of downloading, I've finally installed the game, but, when I click it, a pop-up showed up. It was japanese so I didn't quite understand but I'm pretty sure it was asking for the serial or key code? I closed it and tried running it on adminastrator but it still won't work. My friend suggested that I should go to the properties and set the compatability to Windows 2000 but it still won't disappear. So I tried copy pasting the patch of the game and then a new error popped up. 
 

So... any idea how to solve this problem?

How about you stop messing with the game, reinstall it and enter the serial code? Or find crack from the internets

Uh, the error is in Chinese, and it says "Cannot find 蒼の彼方のフォーリズム.exe" 

I don't know what in the world you tried to do, but I suggest you stop tampering with the game and uninstall it and then reinstall it.
Then look for a crack, as that's the only way to bypass serial codes/region locks.

I also don't know what "patch" you got because there's no English patch for the game.
I thought maybe you grabbed the Chinese patch by accident, but that's also not out either, so I really don't know what you got.
