As you can see many keys are with me considerably more available.
Particularly key 3 seems to be responsible for ensuring that the FF7Config.exe can now put the key correctly, several times (Also present in 32bit system).
If you have a 64bit system, you can try it for yourself.
Set the key as I have, run FF7Config.exe and change there the graphics option to software renderer.
Then you check which key has been changed.
You'll find it is the one of Set 2 and not of Set 1!
And also the game is now using Set 2.
In a 32bit system there is set 2 and set 4 course not, and also set 1 is elsewhere (same structure but without "Wow6432Node").
But Set 3 is also available there.
The UAC popt either way on (even with your patch) because admin rights are needed to re-create keys in Registry.
BTW, if you paste in these keys, you should during the first start of the game experience that FF7Config.exe starts automatically.
This is a sign that now is recognized properly.
