Finding a win7, 64bit compatible version of an old nVidia driver...

So, to make a long story short, I have a computer I'm supposed to fix for a friend. It gets lots of graphics artifacts, black boxes, colored dots, etc. It has an Asrock motherboard (an unusual board with both AGP and PCI-E) and a GeForce 7900gs (AGP).

After much reading, I have determined that this is a solved problem :). Its a driver problem on Asrock boards with nvidia AGP graphics cards. The solution is to install a (very) old version of the nvidia drivers (forceware 97.52). This is described by user Brainwashed here:
Wonky Screen Corruption Problem

But I am having trouble finding and installing a win7, 64bit version of this driver. I know one exists, because in the very next reply in that thread, user Vighi says he found one for Vista64, and it worked (he has win7). But he doesn't give a link to it.

I tried to find one on my own with google. I found this one:
v97.52 VISTA 64bit | Nightly Build - LaptopVideo2Go Forums

But its on a laptop video website, and might be for a laptop video card. Its also a "modified Inf" driver, whatever that means. Anyway, I ran the setup file, but it wouldn't install. In safe mode, it said it couldn't find a driver compatible with my hardware. In normal mode, it says I have the wrong operating system, that it won't work with a 64bit OS.

Thoughts? Its really frustrating having identified the problem, and found a solution that almost everyone says worked for them, but not be able to make it work myself.

Thanks guys!

You can use the vista driver if you install it in compatibility mode

Right click the installer>properties>compatibility>chose vista.

You can use the vista driver if you install it in compatibility mode

I just tried this. It said "setup could not find a driver compatible with your current hardware, setup will now exit." This was in vista service pack 2 compatibility mode, running as administrator.

That was with the 97.52 vista64 driver I found on laptopvideo2go. But this computer is NOT a laptop. So I tried a 97.46 vista64 driver I found on guru3d. (They have a 97.52 driver, but its x86). Same problem, same error.

Thoughts? Thanks guys.

EDIT: that laptopvideo2go driver listed the graphics card (GeForce 7900gs) on its list of compatible cards. See link in my OP.

I had another thought. If the geforce 7900gs is incompatible with that particular driver (it shouldn't be), I do have a geforce 6800 laying around I could try. Would that help? Any other thoughts?

Thanks guys.
