Well, it's not a big deal- I personally hate UAC and don't know why I leave it on at all xD.
Actually, I just disabled it, I've always hated it since I upgraded from XP.
That aside, I've noticed a" bug" with the 64bitpostinstall.bat file.
It attempts to open "%ProgramFiles%\Square Soft, Inc\Final Fantasy VII\ff7_opengl.cfg", which won't work since that is equal to
"Program Files\Square Soft, Inc\Final Fantasy VII\ff7_opengl.cfg", but the opengl.cfg file should be in the Program Files (x86) folder, this aside the whole .bat file runs as it should.
I'm trying to find right path you want without hardcoding it to a specific drive letter, but I can't find anything like %ProgramFiles% that points to the x86 folder..
EDIT: I guess it seems to be "%ProgramFiles(x86)%" but watch out because the last time I put that in my "run" prompt my whole computer crashed :S. Nevermind that crash, I just edited the .bat myself and it worked and opened the config file correctly. My one last question about the bat is, shouldn't it open the "ff7opengl_vista64.reg" file instead of the "ff7opengl.reg" or is that specifically for vista/7 x64, not XP x64?
EDIT EDIT: Nevermind, just realized you took care of the opengl.reg file stuff in the first post install script, all that needs to be changed is that "%ProgramFiles(x86)%"
