Installing the game

Two versions of Koikatsu exist: DVD (physical media) and DL (digital media). The DVD version is a box with two DVD-ROMs containing the installer and its files. The DL version is a download link hosted by DLsoft that leads to a self-extracting executable containing the installer and its files. They do not have the same installation steps, although they are somewhat similar. Follow the steps below that matches your version.

DL version

Extract the files in the illusion_0023.part1.exe self-extracting executable to a newly created or existing folder located in the root directory of any storage drive, for example C:\kksetup or D:\kksetup. As a precaution, the folder's name must not contain non-ASCII characters and spaces to prevent any possible errors. Repeat this step for illusion_0023.part2.rar, illusion_0023.part3.rar, illusion_0023.part4.rar, and illusion_0023.part5.rar.

Afterwards, run ILLUSION コイカツ！.msi and keep clicking (N) until the installer prompts for the game's installation path. It is strongly recommended to use the default installation path. If a different installation path is required, make sure the installation path does not contain non-ASCII characters and spaces or goes through folders that have special access permissions.

DVD version

Insert the ILN108-1 DVD-ROM into an optical drive capable of reading single-layer DVD-ROMs, then run the installer when prompted by AutoPlay. If you have the digital copy of the ILN108-1 and ILN108-2 DVD-ROMs as .iso files but don't have an optical drive or DVD-Rs to burn them on, you must use the mount option to mount the .iso files. Please note that you require at least 7.3 GB of free space for the virtual DVD-ROMs to mount successfully.

Afterwards, keep clicking (N) until the installer prompts for the game's installation path. It is strongly recommended to use the default installation path. If a different installation path is required, make sure the installation path does not contain non-ASCII characters and spaces or goes through folders that have special access permissions. Please note that a prompt asking for the ILN108-2 DVD-ROM to be inserted will be displayed mid-way of the installation process. Follow through and eject the ILN108-1 DVD-ROM to insert the ILN108-2 DVD-ROM. The first DVD-ROM will not be required again.

Installing updates

The game's updates are stored in CubeICE self-extracting executables that may not function or extract correctly on Windows systems with a non-Japanese locale format set. To fix this problem, file archivers such as 7-Zip or WinRAR can be used to extract the updates manually by opening the .exe files like a .zip file. This can be done by renaming the .exe to a .zip or opening the archive via the context menu option.

When the update is opened with 7-Zip or WinRAR, there will be a folder in Japanese which must be accessed. Once accessed, there will be either multiple folders in Japanese or a single setup folder with other non-essential files present.

With a single setup folder present in the update executable

Access the folder and extract the setup folder's contents (not the setup folder itself) to the game's root directory. For example, if the game is located in C:\koikatu, the correct operation would be to extract everything in the setup folder to C:\koikatu. Allow any overwrite/replace operations if prompted.

With multiple folders present in the update executable

Access the folder and extract the setup folder's contents (not the setup folder itself) to the game's root directory. For example, if the game is located in C:\koikatu, the correct operation would be to extract everything in the setup folder to C:\koikatu. Allow any overwrite/replace operations if prompted. Repeat the steps above for the other folder in Japanese.

If a サンプルデータ folder is present, it is optional and can be skipped as it only contains sample character cards, coordinate/clothing cards, or background images. However, if a setup_as folder is present, you must extract its contents if the After School DLC is installed. If the After School DLC is not installed, it must be skipped.

Update installation order

It is strongly recommended to install the updates in chronological order to prevent errors, except for the Darkness DLC due to the 1st edition's late bug fix. The Darkness DLC has to be installed from the 1st, 2nd, and then to the 3rd edition. Shown below is the update list, starting from the top (oldest update) to the bottom (latest update). Please note that all updates are not cumulative, which means they do not contain the contents of older updates. Skipping an update may result in problems if the update itself relies on an older update to function, which is stated in the README in Japanese. The general recommendation to simply install all updates to prevent errors from occurring.

The Virtual Reality (VR) updates can be skipped if you don't have a VR HMD or don't intend on using VR functionality. All updates can be skipped as well if you don't want to update the base game, as they are not required for the main game to function.

If all of the updates are installed correctly, the game should display Ver 5.1 at the bottom right corner of the screen. This only serves as a rough visual indicator that proves the updates are correctly installed, though. It is recommended to test the game's functions before starting a new save or creating a new character.

CharaStudio

CharaStudio is an application that lets you create scenes of characters in customizable backgrounds with decorations, such as objects that appear or don't appear in the main game. Characters can be posed or animated, although animating characters may be quite difficult in comparison to MMD and other similar applications. Screenshot functionality is the same as the main game, and scenes can be saved as .pngs similar to how characters are saved in .pngs. Please note that the base game does not come with CharaStudio pre-installed, you must install it by downloading the first CharaStudio update to access it.

CharaStudio and its respective updates are included with the main game's updates. If it is installed correctly, CharaStudio can be accessed by running CharaStudio.exe, which should be in the game's root directory.

Virtual reality

Virtual reality mode can be accessed by downloading the first VR update, but it is recommended to install all three VR updates along with the main game's updates that they rely on. Please note that not all VR HMDs in existence are officially supported, only the Oculus Rift CV1, HTC Vive Pre, and the HTC Vive are officially supported. Older and newer HMDs such as the Oculus Rift DK2 or HP Reverb G2 may not work correctly. Also, similar to CharaStudio, the base game does not come with VR pre-installed.

VR mode and its respective updates are included separately from the main game's updates. If it is installed correctly, VR mode can be accessed by running KoikatuVR.exe, which should be in the game's root directory.
