I have tried with the latest 475.14 drivers following your instructions. I am unable to run setup as I get an error about certificates. I can manually install the drivers but I get hit with Code 52. I have tried multiple times on a clean Windows 7 Ultimate x64 SP1 install with all updates installed. This includes of course the SHA2 updates.
I have also attempted your files/instructions. As a general update I found the root certificate from digicert and installed it which does make the Nvidia installer function as expected.
However after following your instructions with your files it still resulted in a code 52.
Continuing testing with an RTX 3050 on Windows 7 ultimate sp1 x64
I figured it out, I thought I would reply here and explain what I did to get it working. I used the graphics driver “474.11-desktop-windows7-64bit-international-whql.exe” which I obtained from the NVIDIA website. By default it wouldn’t install. Windows 7 would state that the driver didn’t support this version of Windows. Using Notepad++ I modified the nv_dispi.inf file. I added two lines to the file (see below). The driver is functional and while Windows 7 says its unsigned. Windows 7 does not prevent me from using it.
At line 491 %NVIDIA_DEV.2584% = Section165, PCI\VEN_10DE&DEV_2584
At line 14094 NVIDIA_DEV.2584 = “NVIDIA GeForce RTX 3050”
I thought the same. I reinstalled Windows 7 and with no other changes than the modified INF file the driver installs fine. As you can see the BCD is default and there is no watermark in the corner of the desktop.
I have since installed other applications and no issues. Windows 7 was fully updated before anything else so I have not tested Windows Update since the driver install as it says there are no updates available.
I have tried all the drivers mentioned above, but none of them were able to successfully drive my 3050 graphics card on Windows 7. My graphics card hardware ID is: PCI\VEN_10DE&DEV_25A2&SUBSYS_000010DE&REV_A1
