Things You'll Need
Instructions
Insert the game disc into one of your computer's disc drives. Once the disc loads, double click the "My Computer," or in the case of Windows 7, the "Computer" tab. The drive in which you inserted the game disc will be represented by the game's logo.
Double click the game's logo. You will then be greeted with a small window that asks whether or not you would like to carry out the installation process. The text in this window is written in Japanese. If your computer is not equipped with the Windows Japanese Language Pack, the Japanese text will be represented by gibberish. Click on the left box to proceed with the installation.
Access your "Program Files" folder and locate a folder named "Concealed the Conclusion." Inside this folder are two sub-folders: "MANUAL" and "th_dnh."
Double click the "th_dnh" folder and locate an application file of the same name. Double click this file to bring up the game's title menu.
