  • It's disabled already.

    Finally it's resolved by manually importing following certificates into the Trusted root certificates authorities(mmc).

    1. manifestCounterSignCertificates.p12
    2. manifestSignCertificates.p12
    3. vs_installer_opc.SignCertificates.p12

     goto run -> mmc -> File -> add/remove snap in.. -> select Certificates -> click add -> computer account -> Local Computer -> ok. Next expand Certificates -> right click on Trusted root certification authorities ->all tasks -> Import -> next -> browse certificate location from your hard disk for above mentioned certificates.

  • Hi Rama,

    Thank you for posting in MSDN forum.

    Please check this link , have a try with Gary's solution to disable FIPS compliance:

    1. Run gpedit.msc

    2. Go to Computer Configuration -> Windows Settings -> Security Settings -> Local Policies -> Security Options -> System cryptography.

    3. For FIPS compliant algorithms for encryption, hashing, and signing, please disable it.

    4. Re-run VS installer as administrator.

    Best Regards,

  • I am also trying to install on machines not connected to the internet. On two machines the layout and install worked but on two others I get

    Microsoft.VisualStudio.Setup.Security.ManifestSignatureVerificationFailedException: The installer manifest failed signature validation

    I have tried all of the suggestions above to no avail (I installed certs, I made sure cryptography setting were disabled (actually group policy has this fised to disabled)). I redownloaded vs_Professional.exe and reinstalled certs...etc, etc. etc... Still the same problem.

    Is there any way to just stop it from checking this and install?

    Is there any place to just download the C++ part into an ISO? Anything??

    I need to get past this error by hook or crook. Please help!!!
