"Invalid Signature" for executable file with valid certificate RRS feed

  • Question

  • We ave a developed an application and code signed it with a certificate from Thawte.
    The application is running on Windows 10 on multiple sites, but there is one company where the file always returns "Invalid Signature"  when we try to execute it.
    There is no error for all applications beside one that has the UAC Execution Level "requireAdministrator" set.

    If i right-click to open the properties of the executable, then the certificate status is "Certificate is OK".
    The application runs fine on all Windows versions on thousands of machines. Including some windows 10 machines.

    Just this one app in the domain of one customer fails all the time. If I create a file without a certificate, then I get the same error message. Although that file does not have a certificate any more.
