I would recommend you look at using win_chocolatey to install packages, it does all the work for you so you don’t need to figure out the arguments for a silent installation. In saying that, win_package should still work just find for other installers, you just need to figure out what the silent install options are (or find an MSI which does that for you). Without any further details as to why Stream or After Effects is not installing we can’t help you too much there.
