After starting for the first time, you will be prompted to install DDLC.
Choose a name for the install of the game. This could be the name of the mod you want to play, but can be anything you want. Type this in to the Install Name box.
After you’ve entered a name, a folder name will be automatically generated, but you can change this if you want. Your installs can have the same name, but not the same folder name.
If you want to play vanilla (not modded) DDLC, you can skip this section.
Check the Install Mod checkbox. Another text box will appear - click this and select the mod you want to play. This should be in the form of a
.zip file (other formats like
.7z also work).
The final option you can choose is Global Save.
By default, each install of the game has its own save folder. This allows you to have multiple versions of the same mod installed without having them interfere with each other.
Enabling Global Save disables this feature, and makes your mod save into the ordinary save folder. This allows you to continue a save game from a Steam copy of DDLC, for example.
Typically you will not want this enabled as it may cause issues with some mods.
Click Install to start the installation process. This will take a few minutes, after which you will be taken to the installation overview.
Click Launch to start playing.
