It seems that there is a file that can't be found.
Can you explain what steps you have done to get this result, please?
Which Windows do you have? Windows with jp mode or localemulator?
Did you mount the file Kokorono_Pendulum.iso in Daemon tools?
Inside the new mounted disc in Windows Explorer, go to the folder setup and run install.exe.
I reinstalled the game on my side and the install/start went well.
