I use the disc version (since the game only works with a disc). For some reason, it won't activate because the game can't find any DirectX 9.c adapters to start. And when the laptop tries to run using compatibility settings, it still won't start. Perhaps the adapter got deleted by accident. Anybody got any fixes or what should I do?

Update: I installed the most recent DirectX adapter for the Sims 2 Castaway Stories, yet the still can't recognize it. Maybe I installed it wrong.

First, try patching ythe executable with the 4GB patch: https://ntcore.com/4gb-patch/
Next, try adjusting the game's graphics Rules so that your card is recognised:

Warning: backup your graphics rules files first! I've never tried this mod myself for castaway, but apparently it should recognise the Castaway game. Please others post here is this is incorrect!
