Which registry do i edit? OpenGLconfig or ff7opengl? Also do i open Final Fantasy VII app with Run FFVII-Remix batch or just normally with the shortcut on my desktop? I'd really appreciate the help.
I'm gonna go out on a limb here and say that you installed both the remix patch and then Aali's driver on top of it (or vice versa). If you've got FF7 remix, there's no reason not to use the start menu shortcut that it makes. It makes life easier. If you want a desktop shortcut, then copy the start menu shortcut to the desktop.
Both of those registry files should do the same thing, but if you run ff7config from the start menu shortcut, it'll automatically apply the right registry key after closing.
User Account Control is a feature (though I'd call it a mistake) of windows vista that essentially screws *everything* up. You can turn it off by going to the control panel, then the "users" option, and there should be an easy link that says "turn off user account control".
Also, make sure that the "Prevent rounding errors" option is on in your ff7 OpenGL config file (which you can also get to via the start menu shortcuts).
