I had the same question as Chiggy, I was able to find a documented answer to his first question. Yes the ACT client automatically removes itself "when it is done". see Microsofts ACT FAQ document.

As for the second question i couldnt find any info about Admin rights on the internets. However in my experience i have seen ACT uninstall on machines that have users logged in without admin rights.
