wait a sec, on #9, you guys don't get a uac prompt to run swtor?
i don't actually have to enter a password either but that's because my win user account is admin level. however it still requires admin privileges. i assume tackhisis use an account that isn't an admin for his daily stuff (actually smart, i just don't do it because it's a pita) so then he would need to enter an admin password.
my best guess is it needs admin privs for ipc between the two swtor processes but not sure since from what i understand during most of beta it wasn't required? it sure is a pain in the ass to make it work with my logitech g700. have to run that elevated, too, to map my mouse buttons nicely. haven't tried vent but i hear that's pita, too.
