Many generic Windows installers can be called from the "run" dialogue (SUPER + R) or from the command prompt with the "/silent" option. It's generally undocumented and support is not universal, but it sometimes works. So, if the Immunet installer is called "setup.exe" and resides in the root of drive D:, you'd hit SUPER+R, and type "D:\setup.exe /silent" in the box, then hit enter/OK.
Other commandline options that may get you what you want: /silentinstall or /verysilent or /y
I've not tried any of the above but I've seen and used them for various other installers.
I'm fairly certain Chocolatey makes use of this trick for most installers, so you may want to see if you can find Immunet's NuGet install script on Chocolatey's web site to see how it calls Immunet's installer.
To deploy this on another machine, you'd have a .bat file calling the installer with the correct commandline option, and run that instead of running the installer directly.
This does of course sound a bit like you might be managing some sort of commercial deployment, so if this is the case then AMP will suit your needs better and is of course licenced and supported for such scenarios. Sometimes it's worse to use the wrong tool for the job than to just not do the job at all. If something's worth doing, it's worth doing right. If you're doing this for an organisation, just get AMP.
