Thanks, Guy but I had already explored that and, as GoShen also pointed out, nothing in the output tells me which of the many components are necessary, so I would presume all are, and in which order they need to be installed. The output pretty much just informs me of the need for a parent installer to wrap it all up which is why I was reaching out to see if there is an alternative MSI installer. Because I do not want to have to do manual installations on a few hundred computers when, ideally, I just want to put it in Software Center to make it available on demand for those users who need it.
And sorry for the delay but I just now got a notification that I had a reply to this.
