User Account Control Problem

Ok so I'm not the administrator on my computer, my dad is, and I have been trying to play a game I recently downloaded but every time I try to play it, it asks me if the administrator is ok with the program "making changes" to the hard drive. It's not making changes its just playing the game its already downloaded and intsalled it just wont let me play, so my question is, is there a way to remove User Account Control from just that program? Oh and I'm not sure if you need to know or not but the game is "GunZ" but thats not what keeps getting blocked by user account control, its the program that is used to launch the game called "Reactor". any help would be much appreciated I seriously just wanna play my game, its a good stress reliever. :emotion-5:
