Where are the types of cs2 files, such as Greisaia series files, stored information?

[rev1557]

Bishop and Atelier Kaguya are easy to find the registry, so if I just back up the information registry, I don't have to reinstall the game every time I format my computer.

But this type of cs2 file used in the Grisaia series doesn't know where the file information is, so I have to reinstall it every time I upgrade my computer. I'm going crazy.

After installation, check that it is running, and Windows format and run it, it says that the game is not installed as shown in the picture.

Does anyone know where the information is stored?
