Welcome to the installation guide for Ao Oni, here are the notes:

Notes[]

Only versions of the game made in RPG Maker will require you to download and install the RTP (step 1 above). Check the downloads page for more information.

  • If you are installing and running an older version of the game, you may experience the Missing Text Glitch.
    • This means that you cannot play any Ao Oni games until you reinstall it.
  • Set your system locale to Japanese.
  • Instructions: Ao Oni was created with RPG Maker XP game engine. In order to play, you will need to download and install the RTP (Runtime Package). It does not affect your computer and can be uninstalled at any time. You can download the RTP from this page.  By default, RPG Maker VX Ace is selected.  Be sure to select the RPG Maker XP file.
  • If you should receive an error message "RGSS102e.dll not found" or "unable to find RTP-Standard", it is likely because you installed RPG Maker VX Ace, instead of RPG Maker XP. Refer to the above link and make sure to select RPG Maker XP.
