Alright---
1) To edit the opengl config, just open a notepad and drag and drop the "ff7_opengl.cfg" into and and edit then save. It's just a plain text file.
Here is what I recommend you do- this will be a bit of a hacky task but if this doesnt work, I dunno if I will be able to help you.
1) Back-up your saves folder (...\Square Soft, Inc\Final Fantasy VII\save)
2) Uninstall FF7 using the uninstaller (you have to use the uninstaller, it will clean the reg entries too)
3) Double check that "HKEY_LOCAL_MACHINE\SOFTWARE\Square Soft, Inc." doesn't exist anymore-- if it does, delete it.
4) Delete the Square Soft, Inc folder from your program files folder, completely removing all traces of everything.
5) Reinstall Final Fantasy 7 from the disc, do a full install.
6) Run "FF7Config.exe" (located in ...\Square Soft, Inc\Final Fantasy VII\) and press okay, don't worry about any of the settings. (You can copy back your saves at this point too)
7) Open Winrar and then open Final_Fantasy_VII_Remix_v2-3_Installer.exe, extract all the files in it to ...\Square Soft, Inc\Final Fantasy VII\ (like you normally would, we just dont want the post install script to start right away.
8.) Unrar and copy these files into ...\Square Soft, Inc\Final Fantasy VII\, overwrite any files it asks about (

9) Run ff7remixpostinstall.bat located in ...\Square Soft, Inc\Final Fantasy VII\
10) Browse into the ...\Square Soft, Inc\Final Fantasy VII\movies" folder and run "ff7movkeyC.reg"
11) Enjoy?
And I need to know, I took it for granted before due to your screenshot- but you are installing and running this from a C: drive right?
Also, after looking at the VBS script, I'm not sure why it doesn't install right for you. I think it might have to do with stuff having different names from the english Windows to the version you are running.
^^ Sorry had to change the steps on you, one of the paths was hard coded and I can't test\am having a hard time changing it...
