@Sim_Lucent For setting up TS2, google Sims 2 Graphics Rules Fix. That's the thing that needs to be tweaked. This is the guide I followed with both TS2 and the Ultimate Collection.

Basically, the game is so old that it won't recognise any modern graphics cards amongst other things, but the fixes are fairly straight forward if you follow them step by step. If you try running without the fixes you will notice everything is set to lowest settings, there are no widescreen options and you will probably have big black rectangles under all your sims instead of shadows. This is my game all fixed up, no mods or CC - although I take my screenshots with printscreen and copypaste them into an image program.
