    Get setup.exe from unknown publisher when trying to uninstall program installed from known...


    I downloaded ScanSnap IX500 setup program from internet, and when I installed it, windows verified its signature.

    Something went wrong and I tried to uninstall ScanSnap Manager, but during this process I get: "Do you want to allow this app from an unknown publisher to make changes to your device?".

    More details gives the program location:

    C:\Program Files (x86)\InstallShield Installation Information\{DBCDB997-EEEB-4BE9-BAFF-26B4094DBDE6}\setup.exe

    :)

    Can't run program with 'unknown publisher'

    A little background might help.

    Before you run a program, it's very important to be sure that the program is actually what it claims to be. For example: Just because a file
    calls itself Winword.exe, how do you know it really is Microsoft Word?

    Software developers vouch for their identity by obtaining a digital certificate, which is a proof of identity not unlike a passport or a driver's license. Digital certificates are issued by trustworthy organizations called certificate authorities.

    Most people wouldn't begin to know (and why should they) how to check whether a program they want to run has a valid digital certificate, so the operating system does that for you by consulting the list of known and accepted certificate authorities included
    in the operating system.

    So here's what happened: Windows won't open your program because the certificate authority (the 'publisher') is not, or is no longer, on the list of known and accepted certificate authorities. The publisher might have been known and accepted in an earlier
    list of certificate authorities, but the lists are updated frequently. The April 2018 update, or another update, revised the list of known publishers, and the publisher for your program ain't no longer on it.

    None of this was invented by Microsoft, who is simply complying with internationally accepted standards for safe computing.

    You're seeing the message because Windows can no longer guarantee that the program is safe to use.

    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.
