During the installation of .NET Framework 4.6.2, I got an error:

.NET Framework installation failed: -2146762486. A certificate chain could not be built

    Following OhioDeveloper’s lead, I essentially did the same thing for all the Dell Driver Packages that error on install in this Dell OptiPlex 3040... I bought a couple compact OptiPlex 3040’s from a business that was closing and therefore liquidating all assets

    Ive been Fighting battles on all fronts trying to do a fresh Windows 7, install on the Dell and ran into the same problem... ( Net Framework 4.8 ) throws a ( Root Trust Certificate - Error ), at the start of the install just after it unpacks all the files and checks the host environment.

    First I used ( 7-Zip ) [ freeware ], pointed it to the Net Framework installation file, and told it to extract... 7-zip will create a folder (with matching name) containing all the extracted contents of the file.

    ~ This part may seem “risky” if you are not familiar with opening installation files to see what they contain, but all we are doing here is, manually running, the specific file for your system and ignoring everything else. ~

    Your looking for the ( .MSI ) files. For example....

    Netfx_???????_x64.msi

    There are many files with similar names, they only very in the middle ( ?????? ) pieces and have either ( x86 ) or ( x64 ) in the name.

    
    If you’re on a 32 bit system, use the files with {x86} in the file name.
    
    If you’re on a 64 bit system, use the files with {x64} in the file name.
    
    

    ...at this point, I had no guidance on which of the ( ????? ) variations of the file to use. There were 4 file naming variations.

    CORE / EXTENDED / FULL / PATCH

    These 4 file name variations didn't help at all... I was unsure if this would be an UPGRADE because in reality ( Net Framework 3.something ) is already installed with Windows.

    CORE, is always an important file name, and sounded important, but eluded to nothing really...

    EXTENDED, sounded silly and eluded again to nothing.

    So I picked FULL, in the hopes it would “do it all” and negate the guesswork. So I had settled on the ( ...FULL_x64... ) version.

    So I ran { NETFX_FULL_x64.msi }, and I am happy to report that ( Net Framework 4.8 ) installed with no errors.

    ...Hope this detailed walk-thru helps someone.

    could it create problem to install the same certificate on several systems?

    No, it will not be a problem even if the systems would be connected to the internet in the future.

    When you connect the system to the internet and do the update it could download a pack of trusted certificates. These certificates will be added to the trusted root store. Existing ones will simply be IMO simply replaced.

    I recently ran into this issue with systems behind a firewall that didn't have internet access. I ran /extract on the .NET Framework 4.6.2 MSI and was able to run the x64 installer directly without the certificate check. Maybe not the "right" way to go, but it worked.

    Just wanted to say that I had a similar issue with trying to install .NET 4.7.2 on a Windows Server 2008 R2 box. I had to first upgrade it to Win 2k8r2 SP1, then add the prerequisite update for the d3ddecomplier.dll (KB4019990), THEN I had to load the certificate store as outlined above. It was only after all that that I was able to finally install .NET 4.7.2.

    Had the same problem, almost. visual c++ error 0x800b010a could not find the certificates to download. Installed firefox and then retried to install c++ and problem fixed. Must be firefox browser installs these certificates.

    I also met the same issue in Win 7 sp1.

    The solution is below:

    1. Download the certificate file from Microsoft: MicrosoftRootCertificateAuthority2011.cer

    If the link invalid someday, you can download from MicrosoftRootCertificateAuthority2011.cer - github.

    1. Double click the .cer file downloaded just now, then install the certificate following below captures:

    Step1


    Step2


    Step3


    Step4

    1. Re-install your .NET Framework 4.6.2 installation package.

    Then the problem will be resolved. May it be helpful for you.
