Neufusion

I installed Battlefield 2142 on my Windows Vista Ultimate PC. When I
run it, the UAC prompt pops up and says it needs administrator
priveldeges. I accept and it works.

When a normal (non-admin) user logs into my PC and tries to play, it
pops up and asks for *MY* password to authorize access. I type in MY
password, accept, and it works.

I just got a call on my cell phone - "Hey, I want to play BF2142, what
is your password?". I dont want to give away my password. I want
normal users to always be able to launch the application, even if I am
not there to put my password in.

How can this be done?
