Alternatively, you could replace the graphics save file for the game:
- Download the GraphicSettingsFile.
- In your file explorer, paste the following location:
%localAppdata%\ExoterraFree\Saved\SaveGames
. - If the
SaveGames
folder doesn't exist, please create it. - Paste the downloaded file into that folder. If you already have a save file by that name, overwrite it with the new one.
Please note that I cannot guarantee the game will run correctly on your system, as the error you encountered suggests it may be related to the limitations of integrated graphics.
