I played Postal 2 on my laptop ages ago and i decided to reinstall it and play it again. Although when i try to play it says "Please enable Direct3D acceleration. You can do this by starting dxdiag and enabling Direct3D Acceleration in the Display1/2 tab after installing DirectX 8.1b (or later) and the latest drivers for your graphics card." I have Direct3D enabled and my drivers are up to date. I tried to reinstall it but it still didn't work. I also tried running in different compatibility modes and running as an admin and it still gets the error. Anyone know how to fix this problem?

Have you tried

1.) app compatibility Toolkit (READ THE HELP FILES EXTENSIVELY)
2.) Here has a fix patch for the game:
