1. Uninstall FF7
2. Remove all codecs (not joking), restart Windows
3. Install FF7 with movie player (from install screen), restart could be necessary
4. Install 1.02, set Direct3D
5. Try and run it. If it's just black screen and nothing happens, goto step 7
6. If it leaves immediately, turn that hardware acceleration up so it gets you a black screen problem
7. If black screen problem persist, install upside-down movie patch (
search for upside-down)
At the end, there should be an Eidos logo. If there is still a black screen, follow that list again. Codecs can be installed again after you get FMVs working.
Now, for your problem. You were probably unable to skip the black screen (eidoslogo is supposed to run here) because you have a laptop and there is no numpad enter (the "standard" enter doesn't work). Try pressing Fn button (if you have it) with enter, or any other key that has enter label. You can also use laptop keypad patch (umm... you're on your own finding it) or just buy a decent USB joypad.
