[Solved] Nvidia's latest Graphics Drivers do not work with Win7!

I need a bit of help with the NVIDIA drivers on Dell XPS 15 7590.

as far as I see GTX is detected and works under Win 10 but it’s not detected under Win 7 so the hardware is fine and it’s a software problem.

I tried to add patch for 475.06 and to disable DSE completely (Win 7 is in the test mode) but again it’s not recognised.

It looks like it doesn’t like its id: VEN_10DE&DEV_1F91&SUBSYS_09051028

While VEN_10DE&DEV_1F91 is NVIDIA GTX 1650 the problem can be in SUBSYS_09051028

So the question is what to change in inf files just to try it install under Win 7?

I already added patch to bypass limitation for latest CPUs in Win 7.

What else can it be?

Try older versions. If OEM graph card, you may need to edit *.inf file (e.g. my RTX2060 in a Legion laptop).

I already tried different versions. Nothing worked. And the oldest one is 457.30-notebook-win7-64bit-international-whql.exe
it looks like I need to cheat Nvidia device check as it was discussed above with 30678m-setup-1.exe and 30678m-setup-2.exe
So I suspect that I will need to change more than inf file.
I already tried this combination and this one also:
30678m-setup-1.exe => 30678m-setup-2.exe
It’s the same problem. It doesn’t work.

Finally GTX 1650 on Dell XPS 15 7590 works under Windows 7 !!!

The reason why it wasn’t detected was very simple. It’s not supported by the drivers from nvidia under Windows 7.

If you search in the info files of the latest display driver you will see that device id PCI\VEN_10DE&DEV_1F91 is there but no SUBSYS_09051028 in inf file.

So you need to add it into the info file and make it mapped in nvpcdi.inf to the same variables as for the already supported versions of GTX 1650 in nvpcdi.inf:

%NVIDIA_DEV.1F91.1F91.19DA% = Section054, PCI\VEN_10DE&DEV_1F91&SUBSYS_09051028

Basically I used the same method as fslj6000 in his post from Aug 2024. After the mod driver became unsigned but now GTX 1650 is alive!

So the key thing is that for this relatively new GPU you need to go not for the oldest but for the latest driver and modify it because in the old version it was no support for GTX 1650 on the laptop at all.

DEV_1F91 does not exist at all in the old drivers.

I used 475.14-notebook-win7-64bit-international.exe
