    W7 unable to confirm Driver Signing for video card


    Running Win7 Pro x64, I do have those two SHA-2' KB patches installed, but when I try to install nVidia drivers using DM (no need for that bloated Ctl Panel and all the fluff), the installation goes fine, but on re-boot, DM has a yellow flag with a Driver signing error.

    I did some research with 3 methods to disable driver signing, but 2 of the three didn't work (Command Prompt & Group Policy). The 3rd has to do with using WinRE which I've never done before (or had to). This involves forcing power off re-boots 3 times.
    I also have read that holding F8 during booting does the same thing (I believe).

    Anyone have any input of this??

    If you install a NVIDIA driver for Windows 7 64-bit that's not newer than version 391.35

    you shouldn't have that driver signing issue.

    It's the driver version that I use now for the NVIDIA graphics cards in my Windows 7 64-bit systems.

    The oldest driver I have a copy of is 457.51
    The current version is 475.14.

    The error message in Device Mgr I get is;
    " Windows cannot verify the digital signature"

    I provided you with the download link for the NVIDIA driver for version 391.35, if you want it.

    Here it is again.

    I mis-read your previous post. I missed the "not newer" part. I read it as something newer than that version which I already have..

    Ok, it worked. What's with this older version, why does that work???

    I used DM as I almost always do so all of that other crap doesn't get installed. BUT, it did anyway which has never happened before.
    The following I don't want, can I remove them?;
    3D Vision Driver,
    Physx System Software (nVidia Settings)
    Visual C++ x86
    Visual C++ x64, do I also need x86, or for that matter do I need either?

    Basically, I want to know if they are needed for the actual drivers. I do not game or overclock !!

    Select the custom option instead of the default option.
    Uncheck all boxes, except for the display driver.
    Select the clean install option.
    Doing this will install only the display driver without the unneeded features.

    Since you have already installed the driver, and it is working fine, just uninstall the 2 unneeded NVIDIA features.
    All you need to keep is the display driver and C++ 2013.

    391.35 is the last version released for Windows 7 before driver signing went into effect.
    Driver versions newer than that are effected by driver signing.

    Nice secret, no thanks to nVidia and M$.
    I don't understand why they couldn't be verified?? I got them straight from nVidias site.

    That 3d driver uninstalled fine,
    That system software didn't! It left globs of files that I initially couldn't delete. The DisplayContainer that ran 3 processes couldn't be terminated using Resource Hacker, they kept on re-starting just like a virus would.
    I had to delete the .exe to stop them from loading at startup.
    Twenty years of loading drivers using Device Manager, I NEVER had any of this happen, how the hell the entire package loaded thu DM even when I pointed it to the 'Display' folder is beyond me!

    Next card will be AMD.

    The latest Windows 7 drivers are not WHQL-certified, thus Windows cannot verify the digital signature. The last WHQL-certified one is v474.11. All later versions are basically the same, just include some "security updates" that don't affect performance, etc.

    Visual C++ x86/x64 is not mandatory for the drivers to work, but you can keep it for something else.

    Then why are they released if one can't install them? Am I missing something here??

    They can be installed, but you'd better avoid them. Here's the manual from NVIDIA: Changes to the display driver installation process under Microsoft Windows 7 | NVIDIA
