How to Install the Game Updates
Illusion update files are in the form of an .exe file , which does not always work on computers that are not in Japanese.
A workaround is to open the file as if it were compressed with the program 7-zip (right click -> 7-zip -> Open archive). There may be several Japanese folders within the file.
For each of them, look for the “setup” folder and extract the files inside to your game folder (remember, the game should be installed in C:\illusion\KoikatsuSunshine), and the folder “abdata” and his companions must be extracted to the game folder (where “KoikatsuSunshine.exe” is). If asked, overwrite the files when extracting.
