    Hi,

    We create monthly updates for our software released as MSP files. While we
    use Installshield 2008 to build the MSI installations, we use MSIMSP to build
    the patches. The patches install without issue, however, we have an issue
    signing it. Signtool says that the patch is signed successfully, but Vista
    insists that it is an Unknown publisher. How do we fix this?

    Also, while installing the MSI, it is happily acknowledging our signature,
    but uninstall is not. It insists Unknown Publisher.

    Thanks in advance

    Hi,
    I am facing the same issue.
    When i signed my setup exe on XP using following command,
    signtool sign /f c:\MyCert.pfx /d "My Installer" /p password123 /t http://timestamp.verisign.com/scripts/timstamp.dll /v c:\MySetup.exe
    i got message that it is successfully signed. I also checked installer's property/DigitalSignature tab, It is displaying the certificate is ok.

    But on vista when I run this exe, it display unknown publisher pop up. When I checked installer's property/DigitalSignature tab , it is displaying certificate is not verified.

    But on Windows 7 it is displaying right popup showing correct publisher while running this exe.And also checking installer's property/DigitalSignature tab, It is displaying the certificate is ok.

    So I dont understand this behaviour.

    Thanks in advance.

    to read it after all this time? You EggHeaders are true HoopleHeads.
