    The dpinst.exe from WDK 7.1.0 redist is signed by Microsoft, but when run on Win7 SP1 x64, the UAC prompt says "from unknown publisher". Could anyone tell why?

    After I signed it with my cert, the UAC prompt properly shows my publisher name.

    Thanks,

    You are running the 64-bit dpinst on the 64-bit system, aren't you?

    My question really was making sure that you are using the amd64 version of
    DPInst.

    Yes, Tim, it is amd64 version. Tested also on 2008R2.

    When I view the signature in the file properties, it says the signature is OK.
