    Unknown Publisher when trying the installer(exe/msi) on windows 10

    I'm using Visual Studio 2019 and have build "Installers(msi/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" /tr
    http://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

    Is it expected behavior when a Windows 8.1 iso file says Unknown Publisher?

    Finding .IMG or .ISO file in Windows 8.1 Pro download

    Hey guys,

    In preparation for my new PC I downloaded Windows 8.1 Pro from Dreamspark, and I wanted to burn it to a DVD, so I can install it on the new PC.
    However, in the downloaded files I can't find a .IMG or .ISO file anywhere. I understood that the .IMG file is the one you need to burn to the DVD?

    Any suggestions?

    Thanks in advance!
