As the installer is running, it asks for agreement to a license for some sort of player. I suspect that the player contains spyware, but I don't have a spare system here to allow it to install.

You do not appear to need to accept the license (and install the player) to have it unpack the files.

LawnDartLawnDart, have you run Ad-Aware on the system on which you ran the installer? (Did you accept the player?)
