dovholukspam,
1) Why do you read "stardock software" as spyware out of curiosity? FWIW, it isn't, it's an installer program for all the various programs Stardock offers that includes the ability to buy (with CC or with TotalGaming.Net tokens) their software from within the installer, or to install demos of the same software, where available.
2) That question has already been asked and answered in this thread, see message #43 for the answer.
Edit: Oops, got called away from my desk while composing, so I didn't see your second post. As for needing to be admin, I don't know, I gave up on trying to use non-admin users when even MS games required admin privledges to play, let alone install.
