    We keep on getting signature verification issue while trying to install IIS compression module using Web Platform Installer. I've tried different machines but they all failed with below message:

    <div>PS C:\Program Files\Microsoft\Web Platform Installer> .\WebpiCmd.exe /install /products:"IISCompression" /AcceptEULA /Su

    Web Platform Installer is known to have issues these days.

    To install IIS features via command line, you should follow https://docs.microsoft.com/en-us/iis/install/installing-iis-7/installing-iis-from-the-command-line
