Ok, so I have the Sims 2 and a good number of expansions: University, Nightlife, Seasons, Open for Business, Pets, and Bon Voyage. Everything installed fine without out a problem. But when I try to run it I get the Directx 9.0 error stating that I do not have Directx 9.0 or a compatible video device. My System: Gateway FX 7805u Laptop 4gb DDR3 RAM Centrino 2: 2.26 dual core P8400 chip set GeForce 9800 GTS 1gb card 320gb HD I'm running: Windows Vista Home Premium 64bit Directx 10 Directx Diag tool claims I have: Nvidia GeForce 9800 gts Integrated RAMDAC 2799 mb (Graphics card) What I've tried: Updating card drivers Updating Directx (From Microsoft) Reinstalling Directx Reinstalling The Sims 2 I've checked everything I can find online, I see people having the problem but nothing has been able to resolve mine. I don't know what else to try, Maxis claims that Sims 2 is Vista compatible but maybe it's not 64 bit compatible? Or maybe it's this graphics card? Or maybe it's because I have Directx 10...I'm at a lose. Thanks for your help and input.
