Q: Bootcamp driver update for Windows 10 bad signature

The update of the Bootcamp driver for Windows 10 does not install. Windows' error message says the signature is faulty and deletes the half downloaded file. I tried to update three times but the error occurs every time. What can I do to install the update?

iMac (27-inch, Late 2012), OS X El Capitan (10.11.1), 32 GB RAM, Nvidia GeForce GTX 680MX

    It is in German. The translation is the very message I posted already.

    1. Is this from the Apple Software Update from W10 side?

    2. Is a specific driver failing.

    3. Can you right-click on the specific driver that fails and post the version number?

    4. If you BC Assistant to download the Windows support software, what is the Product version in Bootcamp.xml?

    1. Yes.

    2. Yes.

    3. It is Apple Boot Camp for Windows 10, version 6.0

    4. Build Numer 6136, Version 6.0.6136

     

    I downloaded the driver via Boot Camp Assistant under Mac OS X. Then I startet the setup.exe under Windows. It installs for a little while and brings up the same error message as it does when I try to install it via the Apple Software Update program in Windows 10. It is a rather big error message (see screenshot in German). It reads that the installed product does not match the installation source. Unless the source can not be found the installation cannot be completed. I can manually find the source (BootCamp.msi). When I do so the same error message pops up.Foto Windows.JPG

    The Product Version of 6.0.6136 is valid for W10. I will check if it is valid. Can you install a specific drive, for example, try the keyboard driver?

    No, the installer says I don't have enough privileges and have to use setup.exe.

    Does your current Windows account have Administrative rights to the W10 installation?

    I don't know. It is the only account and never made any problems with Apple's software updates.

    I downloaded the latest BC Drivers package for your iMac model. Your version dated - 2016-04-01 22:22:52 - is the latest.

     

      <MsiInfo>

      <ProductManufacturer>Apple Inc.</ProductManufacturer>

      <ProductVersion>6.0.6136</ProductVersion>

    <ProductCode>{FCFFE6B6-BAE8-490E-88D0-097A9DA1C43D}</ProductCode>

     

    Are you familiar with Brigadier - https://github.com/timsutton/brigadier ?

     

    You can try the drivers for the 21.5 in iMac Late 2012, but create a Windows System Restore point before you test this version.

    I don't know Brigadier. I think, it is too hot for me to fiddle around with Windows. I will wait until Apple fix the update and it will work as intended. Thank you for your help.

    Can you test the same package installation under

     

    1. SIP disabled. Boot in Local Recovery and run csrutil disable. Boot normally and retry the installation. You can re-enable it using the csrutil enable. Please also see About System Integrity Protection on your Mac - Apple Support .

     

    2. Try the following two procedures and retry your package installation.

         Reset the System Management Controller (SMC) on your Mac - Apple Support

    Why should I disable SIP for installations within Windows? The system protection is for software running in Mac OS X, isn't it? Resetting the SMC does not help either. It is obviously a user privileges issue in Windows.

    Irrespective of which OS you use, the device drivers have common information which is stored in NVRAM. You can see it partially in nvram -p output. When drivers are installed, some of them allow common settings. One example is Audio Volume DB, Bootcamp is another. You are disabling SIP for the duration of the installation only.

     

    The privilege issue is the reason for asking if you have Admin rights to your machine. Domain Controlled Windows accounts may remove such rights from logins based on AD groups.

     

    Have you been successful in installing drivers in the past? Is Windows set for Automatic Updates? If you have manually disabled W10 Drivers update, it can cause problems as well.

    As I already wrote, I had never any problems with updates, especially Apple software, under Windows. The machine is configured to update automatically. It is the first time I see this error message.
