My apologies—I gave you slightly wrong instructions in my last message. There is no separate textures folder to download because I packed all the textures directly inside the main file.
Since it's still showing up purple for you, two things might be happening:
1. If you imported the .fbx or .obj file into Blender, it will often turn purple. Instead, try directly opening the "Vice City.blend" file.
2. If you are opening the .blend file directly and it's still purple, you might be using a newer or older version of Blender that isn't reading the packed textures correctly. Try changing your Blender to the blender 3.0 version!
