    Unknown Publisher for when trying the installerexe/msi


    I'm using Visual Studio 2019 and have build "Installersmsi/exe" using "Setup Wizard".
    When i'm running the set.exe installer, the application "publisher" is being reported as "Unknown".
    I've gone through some references and found that the setup.exe needs to be digitally signed with the certificate. So,
    i have followed below steps to add digital signature to the setup.exe
    1. Create Digital certificate https://knowledge.digicert.com/solution/SO26065.html
    2. Using signtool i have digitally signed setup.exe
    signtool.exe sign /f "E:\sample.pfx" /p "sample@123" /trhttp://timestamp.comodoca.com/rfc3161 /v "E:\setup.exeWhen i try to run setup.exe locally, the application "publisher" is reported as "localhost" instead of "Unknown", but if i
    run the same setup.exe on another system application "publisher" is reported as "Unknown"Please provide any suggestions on fixing this "Unknown Publisher" issue

    :)

    MSI & EXE installation throwing pop up as unknown publisher on Windows 10 - 1607 and 1709 update

    I am trying to install an EXE which is a wrapper to the MSI on Windows 10 - 1607 and 1709 versions of OS which is throwing a pop up as
    unknown publisher. (both EXE and MSI is throwing the pop up)

    We have the .pfx files and the installer should not show unknown publisher.

    NOTE: this issue was not observed in the previous version of Windows(7 & 10).

    Please let us know if there is any specific UAC changes as part of these latest WIN10 updates and workaround for the same.

    unknown publisher

    Hey, J.K. Rowling was an unknown publisher before Harry Potter, and look what happened to her.

    But in your case, the 'unknown publisher' refers to the security certificate that vouches for a software program. These certificates need to be renewed annually or they become invalid, and Windows won't run software with an invalid security certificate.
    CM Tray is part of a very old program. Upgrade to the most recent version of the program, which will likely have a valid security certificate.
